200533788 (1) 九、發明說明 【發明所屬之技術領域】 本發明是關於：金屬或合金製的連續長條形構件、或 者以金屬或合金製之複數被處理構件作爲構成要件之連續 連結的被處理材，譬如含有金屬或合金製鏈齒和止檔部（ 上止檔部、下止擋部）的接合器鏈、和以金屬或合金製球 構件作爲構成要件之連續連結的球鏈等金屬或合金製被處 理材的電解方法及其裝置。 【先前技術】 一般的電解處理（陽極氧化、電解電鍍）的執行方式 ，是將欲進行表面處理的被處理材作爲其中一個電極，並 與另一個電極一起浸漬於相同的電解浴中而對上述兩者之 間通電。 但是，當以複數個金屬構件作爲構成要件的被處理材 ，譬如大量的鏈齒（齒條）以一定的間隔固定於接合器帶 之長軸方向其中一端緣所構成之拉鏈的接合器鏈、和利用 線之類的連結構件連結大量球構件而成的球鏈等時，由於 各構件之間（譬如相鄰的鏈齒之間）無法形成電氣連接， 故難以利用上述的一般方法執行電解處理。 因此，對上述由複數個金屬構件所構成之被處理材的 構成構件進行表面處理的方法，則是在把接合器鏈捲繞於 非導電性圓筒形保持具外周，進而將電氣導體線捲繞於各 金屬鏈齒上形成接觸（請參考日本特許出願公告：昭3 6-2 5 7號公報）；或將結合器鏈捲繞於導電性保持具（請參 200533788 (2) 考日本特許出願公告：昭3 6 - 1 1 8 7 1號公報）；或者近一 步僅將鏈齒組裝於導電性的保持槽（請參考日本特許出願 公告··昭3 3 - 1 4 5 9號公報），並在金屬製鏈齒之間形呈電 氣連接的狀態下以批次（batch )的方式執行處理。 但無論上述的的哪一種方法，都是使電極構件（電氣 導體線、導電性保持具或者導電性保持槽）直接接觸於鏈 齒部分後通電的方法，而具有電極構件與鏈齒之間的接觸 容易產生不一致，容易在陽極氧化皮膜等電解處理所形成 的皮膜上產生斑的問題。此外，由上述的方法均形成批次 處理，故生產性不佳。 因此，也執行一種：鏈齒之間在預先形成電氣連接的 狀態中製作接合器鏈，並對該接合器鏈連續執行電解處理 的方法。舉例來說，藉由將導電線編入接合器代的鏈齒組 裝部內而在各鏈齒間形呈電氣連接的狀態下製作接合器鏈 (請參考日本特許第25 1 760號公報），具有上述導電線 的接合器鏈，是藉由導引滾子的導引一編通過電解浴中一 邊形成連續搬送，而執行連續電解（請參考日本特許公開 公報：2003 - 1 93 293號公報）。 在上述方法的場合，雖然可對鏈齒列同時通電，而可 連續執行電解處理，但導電線的價格昂貴’此外，由於編 入金屬製導電線，在帶的製作及染色的過程中容易引起導 電線的斷裂及金屬的熔解等，而具有生產性不佳的問題。 而其他爲業界所熟知的方法’是預先以滾商電鍍等方 法對拉鏈的鏈齒和止擋構件（上止擋部、下止擋部）、及 -5- 200533788 (3) 如球鏈之球一般的複數微小構件進行電鍍。 但是，一般的滾筒電鍍場合中，由於電流容易在電解 液中流動，而難以充分流到被處理材的附近，不僅附著性 不佳，且具有容易產生著色斑紋的問題。此外，當預先對 鏈齒電解處理後，將其固定於接合器帶以製作接合器鏈的 場合中，相較於一般接合器鏈的製作方法，也就是在切斷 剖面形狀相當於鏈齒剖面形狀的線材（所謂的Y桿）的同 | 時固定於帶部方法，其步驟繁瑣且耗時而導致製造成本偏 高。 【發明內容】 〔發明欲解決之課題〕 本發明是有鑑於上述傳統技術之問題所硏發而成的發 明，本發明的目的是提供一種：針對含有金屬或合金製鏈 齒及止擋構件（上止擋部、下止擋部）的接合器鏈；和以 φ 金屬或合金製的球構件作爲構成要件而連續連接所構成的 球鏈等物的電解處理，可解決以電極直接接觸金屬或合金 致被處理構件進行處理時的不一致性，且不需採用導電性 線對鏈齒列形成電氣連接即可進行處理，並能以低成本且 有有效率地於被處理材表面執行均勻電鍍處理的方法及其 裝置。 〔解決課題之手段〕 爲了達成上述目的，根據本發明的第1個特徵所提供 -6 - 200533788 (4) 的電解處理方法，其第1個樣態’是採分隔電解液的方式 ，僅使來自於實質上應進行處理之被處理材的構成要件間 及/或其周圍的縫隙的電解液流通地將被處理材配置於電 解浴中，並於被處理材兩側配置一對互相分離的電極，而 對該電極供電來執行電解處理。 該方法可適用於連續處理’可以使上述被處理材一邊 移動一邊執行連續的電解處理。 P 本發明之電解處理方法的第2樣態，實質上僅使來自 於被處理材間及其周圍縫隙的電解液流通地，將由複數個 被處理構件所形成、或含有複數個被處理構件的被處理材 ，容納在電解液可流通之電氣絕緣性被處理材容納槽內， 將被處理材配置成分隔電解液，並於被處理材兩側配置一 對互相分離的電極，而對該電極供電來執行電解處理。 無論上述的哪一個樣態的電解處理方法中，其供電方 法可採用：使直流、或電壓或電流正負交替逆轉的正負對 φ 稱或者正負非對稱的波形（交流、脈衝型波形、鋸型波形 等）。特別適合的供電方法，是重複1次或2次以上循環 的方法，該循環是於輸入使直流、或電壓或電流正負交替 逆轉的正負對稱的波形一定時間後，反轉輸入的對極並加 以通電。 前述的被處理材，只要至少一部分爲金屬或合金製便 全部可適用’本發明的電解處理方法，是適用於以金屬或 合金製之連續長條形構件、或者以金屬或合金製之複數被 處理材作爲構成要件所連續連結而成的被處理材，特別是 200533788 (5) 含有金屬或合金製鏈齒甚或止擋精 止擋部）的接合器鏈、和以金屬或 要件之連續連結的球鏈。 此外，本發明的電解處理方法 解電鍍、電解硏磨、電解脫脂等所 表面改質方法。 雖然電解處理的條件，可對應 g 等作適當的設定，但是當被處理材 處理構件作爲構成要件，且對其執 好是採用使直流和1 0 k Η z以下頻率 並以2 0 V以上的電解電壓執行陽極 此外，當上述電解處理爲電解 氧化鉀及/或氫氧化納的電解浴中， 頻率正負交互反轉的波形來執行電丨 再者，當上述被處理材含有銅 φ 製的被處理構件作爲構成要件，且 最好是採用使直流和10Hz以下頻 執行電解電鍍。 而當上述電解處理爲電解脫脂 紳及/或氫氧化納的電解浴中，採用 正負交互反轉的波形，並以5 V以 脂° 根據本發明的第2個特徵，是 解處理方法的電解處理裝置，其第 |件（上止擋部及/或下 合金製球構件作爲構成 ，適用於陽極氧化、電 有電氣性執行被處理材 被處理材的型態、材質 含有以鋁或鋁合金之被 行陽極氧化處理時，最 正負交互反轉的波形， 氧化處理。 硏磨時，最好在含有氫 採用使5Hz〜200Hz之 摔硏磨。 丨-鋅合金、不鏽鋼和鋅 對其執行電解電鍍時， 率正負交互反轉的波形 時，最好在含有氫氧化 使100Hz〜1kHz之頻率 下的電壓來執行電解脫 提供可良好執行上述電 1樣態的特徵爲具有： -8 - 200533788 (6) 電解槽；和配設成分隔該電解槽的分隔壁，該分隔壁具有 可供電解液流通的開口部、及形成於壁內面且橫切過該開 口部的被處理材插通部；及分離配置於該分隔壁兩側的一 對電極。而最合適的樣態，是於上述電解槽的下方配置漏 液承槽，並於電解槽與漏液承槽之間，設置可將上述漏液 承槽內之電解液送入上述電解槽的循環線。 此外，本發明之電解處理裝置的第2樣態，其特徵爲 _ 具有：電解槽；和配置成分隔該電解槽，且可供電解液流 通之電氣絕緣性被處理材容納槽；及分離配置於該被處理 材容納槽兩側的一對電極。而合適的樣態中，上述的被處 理材容納槽爲圓筒狀的多孔迴轉滾筒，最好該多孔迴轉滾 筒的內面形成有複數個突起。 〔發明的效果〕 根據本發明之電解處理方法的第1樣態，由於是採分 φ 隔電解液的方式，僅使來自於實質上應進行處理之被處理 材的構成要件間及/或其周圍的縫隙的電解液流通地將被 處理材配置於電解浴中，並於被處理材兩側配置一對互相 分離的電極，而對該電極供電來執行電解處理，故使電流 容易通過被處理材與電解液間的界面附近。因此，可使電 解處理更有效率以執行一致的電解處理，且電解浴的濃度 可較傳統電解處理更低。此外，當執行接合器鏈或球鏈的 陽極氧化處理或電解電鍍時，不必採用如導電線般高價的 材料，只須於傳統步驟中增加處理步驟便能執行效率良好 -9 - 200533788 (7) 的電解處理，可形成顏色一致且具有絕佳耐久性、耐蝕性 的皮膜，進而提供被賦予各種裝飾性的接合器鏈與球鏈。 此外，藉由一邊移動上述被處理材一邊執行連續的電解處 理，可執行生產性佳且成本較低的電解處理。 根據本發明之電解處理方法的第2樣態，由於被處理 材被配置成分隔電解浴，並在容納於電解液可流通之電氣 絕緣性被處理材容納槽內的狀態下執行電解處理，雖然形 成批次處理，但由於實質上僅使來自於被處理材間及其周 圍縫隙的電解液流通地容納被處理材，即使在上述的場合 中，電流也能輕易通過被處理材與電解液間的界面附近。 因此，可使電解處理更有效率以執行一致的電解處理，且 電解浴的濃度可較傳統電解處理更低。此外，當對接合器 鏈的鏈齒、球鏈的球構件、按壓式鈕扣、鉚釘等小型金屬 或合金製的被處理構件執行陽極氧化處理或電解電鍍時， 可形成顏色一致且具有絕佳耐久性、耐蝕性的皮膜。 根據本發明之電解處理裝置的第1樣態，可對金屬或 合金製的連續長條形構件、或者以金屬或合金製之複數被 處理構件作爲構成要件之連續連結的被處理材，執行生產 性佳且成本較低的電解處理。此外，根據於電解槽的下方 配置漏液承槽，並於電解槽與漏液承槽之間，設置可將上 述漏液承槽內之電解液送入上述電解槽的循環線的合適樣 態’能有效率地使用電解液，也能減輕廢液處理的負擔。 根據本發明之電解處理裝置的第2樣態，雖然是形成 批次處理，但可使電解處理更有效率以執行一致的電解處 -10- 200533788 (8) 理。此外，在上述被處理材容納槽爲圓筒狀的多孔迴轉滾 筒’且該多孔迴轉滾筒的內面最好形成有複數個突起的樣 態中’由於具備能有效率攪拌容納於被處理材容納槽內之 被處理材的被處理材攪拌手段（上述的突起），故可更近 一步提高電解處理的一致性。 【實施方式】 p 如上所述，本發明的電解處理方法及裝置，並非使電 極接觸被處理構件，也未採用導電線等特別的材料，而是 利用電解浴中供電的方法執行電解處理，由於僅使來自於 被處理構件間及其周圍縫隙的電解液流通，電流可輕易通 過被處理構件與電解液間的界面附近。如此一來，可執行 處理一致的電解處理，此外，電解浴的濃度可較傳統電解 處理更低。 而所謂僅使來自於被處理構件間及其周圍縫隙之電解 φ 液流通的手段，第1樣態是採分隔電解液的方式，僅使來 自於實質上應進行處理之被處理材的構成要件間及/或其 周圍的縫隙的電解液流通地將被處理材配置於電解浴中。 另外，第2樣態是實質上僅使來自於被處理材間及其周圍 縫隙的電解液流通地，將由複數個被處理構件所形成、或 含有複數個被處理構件的被處理材，容納在電解液可流通 之電氣絕緣性被處理材容納槽內，並將被處理材配置成分 隔電解液。 以下，就圖面中所顯示之本發明的最佳實施樣態進行 -11 - 200533788 (9) 說明，並針對本發明作詳細的說明，然而，本發明並不侷 限於以下的實施形態。 首先，第2〜4圖，是顯示適用於··以金屬或合金製的 連續長條形構件、或者以金屬或合金製之複數被處理構件 作爲構成要件所連續連結而成被處理材，舉例來說，以含 有金屬或合金製鏈齒和止擋部（上止擋部、下止擋部）的 接合器鏈、和以金屬或合金製球構件作爲構成要件之連續 g 連結的球鏈作爲被處理材，且剖面形狀相當於鏈齒剖面形 狀之線材（所謂的Y桿）的電解處理裝置的範例。其代表 例，也就是拉鏈之其中一例的槪略結構圖如第1圖所示。 如第1圖所示，接合器鏈1是由：芯部3形成於其中 一端緣側的接合器帶2 ;和以一定間隔鉚合固定（固定不 動）於上述接合器帶2之芯部3的鏈齒（鏈齒條）4 ;及 進一步被鏈齒條鉚合固定於接合器帶之芯部3的上止擋部 5與下止擋部6所構成。拉鏈是由：彼此形成對峙的一對 φ 接合器鏈1 ;及配置於上述鏈齒4之間，可自由滑動於上 下方向，並用來執行鏈齒間之嚙合與分離的拉頭7所構成 。此外，固定於接合器帶2之芯部3的鏈齒4的型態中， 除了線圈狀的鏈齒條外，還具有圖面內容以外的各種型態 ，無論是上述的哪一種均可適用於本發明。 第2圖，是顯示電解裝置本體的槪略結構。電解處理 裝置20的電解槽2，是由分隔壁22劃分成2部分。分隔 壁22具有：可供電解液流通的開口部23 ;及橫切過上述 開口部2 3，並貫穿略垂直方向後形成於分隔板2 2內的被 -12- 200533788 (10) 處理材插通部24。此外，圖示的範例，是揭示接合2個槽 的側壁而製作成1個電解槽的範例。換言之，是預先在上 述2個槽之側壁的相對位置處貫穿設置開口部，並於接合 2個側壁時形成開口部2 3，此外，預先在2個側壁之相對 部分的垂直方向上形成凹溝，而於接合2個側壁之際形成 分隔壁22，並同時在上述分隔壁之間形成被處理材插通部 24。本發明並不侷限於上述的製作方法，亦可將預先形成 有開口部23、及橫切上述開口部23之被處理材插通部24 的分隔壁22，配置於1個電解槽21內以劃分成2個槽室 〇 此外，分別將電極25a及25b配置於分隔板22兩側 的槽室內，並使電極25a及25b連接於電源26。而電極 2 5a、25b的尺寸，最好是形成開口部23之尺寸以上的尺 寸，而其位置可任意設定，只需位在從分隔壁2 2兩側分 離，且相互對峙之電極2 5 a、2 5 b的投影面積可覆蓋開口 部23的位置即可。 此外如第3圖所示，在上述電解槽2 1的下方配置漏 液承槽2 7，並於該漏液承槽2 7與電解槽2 1之間設置循環 線2 8，漏液承槽2 7內的電解液L是藉由泵2 9送入上述 電解槽21。 而形成於分隔壁22之被處理材插通部24的尺寸（寬 度及深度），是設成較被處理材之寬度及厚度更大，此外 ’開口部23的尺寸可對應被處理材的大小作適當的設定 。舉例來說，當被處理材爲接合器鏈1而被處理構件爲鏈 -13- 200533788 (11) 齒4時’開口部23的寬度是在一對接合器鏈〗嚙合的狀 態下’設成略等於雙方鏈齒4的之合計寬度或者略大於上 述合計寬度的尺寸。藉由設成上述的尺寸，能僅使實際上 欲執行處理之接合器鏈1的鏈齒4部分浸漬於電解液中， 故可將滲入接合器帶2後被取出之電解液的量抑制到最低 ，也能防止接合器帶2的劣化。在電解處理時，由於僅使 實際上來自於該鏈齒4 (被處理構件）周圍及/或鏈齒4間 之間隙的電解液流通，故電流可輕易通過鏈齒與電解液的 界面附近。因此，能使電解處理變的有效率，並可執行一 致的電解處理。 在電解處理時，是如第3、4圖的箭號所示，使插入 被處理材插通部24的接合器鏈一邊朝下方依序搬送，一 邊連續執行電解處理。此時，雖然電解液L從被處理材插 通部24下端的開口洩漏，卻被回收入配置於下方的漏液 承槽2 7內。被集中於漏液承槽2 7內的電解液L，是由泵 2 9送入上述電解槽2 1。 雖然在上述的樣態中’是將漏液承槽2 7配置於電解 槽2 1的下方，但亦可形成將內槽（相當於電解槽）配置 於外槽（相當於漏液承槽）內’而從內槽（電解槽）之被 處理材插通部下端開口部運出的接合器鏈’則藉由導引滾 子一邊從內槽與外槽間朝上方導引一邊搬運。在上述場合 中，由於內槽與外槽是利用被處理材插通部的下端開口部 形成連通，電解液的液面因內槽與外槽而形成同一個面’ 故不需要上述的泵29 ° -14- 200533788 (12) 本發明的電解處理方法，是根據電解浴中供電 ，在此列舉陽極氧化時的範例作說明，舉例來說， 電源對兩電極25a、25b供電，以其中的一個電極 爲陽極，而另一個電極25b則作爲陰極，鏈齒4位 25a側的表面帶負電，於電極25b側的表面帶正電 極2 5 b側的表面氧化後形成陽極氧化皮膜。相反地 以電極2 5 a作爲陰極，另一側的電極2 5 b作爲陽極 鏈齒4位於電極2 5 a側的表面帶正電，於電極2 5 b 面帶負電，令電極25a側的表面氧化後將形成陽極 膜。如此一來，將可於鏈齒4的整個表面形成陽極 膜。該電解浴中供電的原理，並不侷限於陽極氧化 是可適用於電解電鍍、電解硏磨、電解脫脂等電氣 理材表面改質的所有方法。 第5及第6圖，是顯示適用本發明電解處理方 鏈的其中一例。該球鏈3 0具有：利用連結構件3 2 數個金屬或合金製中空球形之球3 1的結構。當利 電解裝置2 0對該球鏈3 0執行電解處理時，是拉齊 鏈形成略等同於開口部23的寬度後通過被處理材 24，一邊朝下方搬送一邊連續執行電解處理，在上 合中，由於電解處理時也是僅使實質上來自於球鏈 處理材）周圍及/或球3 1間之縫隙的電解液流通， 可輕易通過球鏈3 0與電解液間的界面附近。因此 電解處理變的有效率，並可執行一致的電解處理。 當對Y桿之類的線材進行電解處理時’開口部 的方法 由直流 25a作 於電極 ，使電 ，倘若 ，將使 側的表 氧化皮 氧化皮 處理， 性被處 法之球 連結複 用上述 數條球 插通部 述的場 30 (被 故電流 ，能使 23的 -15- 200533788 (13) 尺寸只需設成：位於插入被處理材插通部2 4內之Y桿與 開口部2 3間可供電解液流通之間隙般大小即可。此外， 當對上述線狀被處理物執行電解處理時，可藉由使被處理 物一邊轉動一邊搬送的方式，執行更適宜的電解處理。 第7及第8圖，是顯示適用於對上述接合器鏈1之鏈 齒4之類的構成構件、或球鏈3 0的球3 1、或按壓式鈕扣 、鉚釘等小型金屬或合金製的被處理構件執行電解處理之 _ 本發明電解處理裝置的其中一例。在該電解處理裝置20 中，電解槽21是由具有開口部23的分隔壁22劃分成2 個槽室，而可供電解液流通之圓筒狀電氣絕緣性被處理材 容納槽40，是以其迴轉軸4 1爲中心而可自由迴轉地配設 於上述開口部23。被處理材容納槽40是圓筒狀的多孔迴 轉滾筒，其外周壁及內周壁呈網眼狀，而可供電解液流通 。此外，外周壁及內周壁亦可由多孔板形成。於被處理材 容納槽40的內周面，形成有實質上遍佈於其整體長度的 φ 複數的突起（突條）42。此外，與上述實施樣態相同，於 該被處理材容納槽40的兩側配置一對彼此分離的電極25a 、2 5b，並使該對電極連接於電源26。 在具有上述結構的電解處理裝置20中，最好是調整 電解液L的液面高度，使其略等於電解處理時產生迴轉之 被處理材容納槽4 0內全體被處理材1 0的高度。藉此，由 於能僅使實質上來自於被處理構件間及其周圍間隙的電解 液流通，故電流可輕易通過被處理構件與電解液間的界面 附近。如此一來，能使電解處理變的有效率，並可執行一 -16- 200533788 (14) 致的電解處理。此外，由於在被處理材容納槽4 0的內面 形成有複數個突起（突條）42，能有效率地攪拌容納於被 處理材容納槽40內的被處理構件，因此能更進一步提高 電解處理的一致性。 無論在上述哪一種樣態的電解處理方法中，其供電方 法均可採用使直流、或電壓或電流正負交替逆轉的正負對 稱或者正負非對稱的波形（交流、脈衝型波形、鋸型波形 _ 等）。而特別適合的供電方法，是重複1次或2次以上循 環的方法，該循環是於輸入使直流、或電壓或電流正負交 替逆轉的正負對稱的波形一定時間後，反轉輸入的對極並 加以通電的方法。在第9、1 0圖中顯示幾種波形的範例。 第9 ( A )圖是顯示直流波形，（B )〜（D )爲正負對 稱的波形，其中（B )爲交流波形，（C )爲脈衝波形，（ D)爲鋸型波形，此外（E )則爲脈衝非對稱型波形。 另外，第1 〇圖則顯示交流非對稱型波形，是使負絕 I 對値大於正絕對値的（a )波形、與負絕對値小於正絕對 値的（b )波形重複交替後執行電解處理。 藉由以上述正負非對稱的其中一種波形作用一定時間 後，重複使正負彼此交替而作用的通電循環，可充分地深 入鏈齒嚙合部分執行電解處理。 此外，本發明的電解處理方法，可適用於：在含有硫 酸、鉻酸、磷酸、草酸、丙二酸、順丁烯二酸、胺基磺酸 等礦酸或有機酸之1種或2種以上的酸性水溶液中執行電 解處理形成陽極氧化皮膜，或利用含有硫酸及磷酸的酸性 -17- 200533788 (15) 電解浴、含有氟酸的中性電解浴等執行電解處理而形成著 色氧化皮膜的陽極氧化處理；或者在含有鎳、鉻、金、銀 等金屬離子或金屬化合物離子的電解液中執行電解處理的 電解電鍍（電沉積）；在氫氧化鉀、氫氧化納等鹼性水溶 液中執行電解處理的電解硏磨或電解脫脂等所有執行電氣 性被處理材表面改質的方法。由於上述各處理方法已爲業 界所熟知，故省略其說明。 雖然電解處理的條件，可視被處理材的型態、材質等 作適當的設定，但是當被處理材含有以鋁或鋁合金之被處 理構件作爲構成要件，且對其執行陽極氧化處理時，最好 是採用使直流和10kHz以下（0〜10kHz)頻率正負交互反 轉的波形，並以2 0 V以上、5 0 V以下的電解電壓執行陽極 氧化處理。 此外，當上述電解處理爲電解硏磨時，最好在含有氫 氧化鉀及/或氫氧化納的電解浴中，採用使5Hz〜200Hz之 頻率正負交互反轉的波形來執行電解硏磨。 再者，當上述被處理材含有銅-鋅合金、不鏽鋼和鋅 製的被處理構件作爲構成要件，且對其執行電解電鍍時， 最好是採用使直流和10Hz以下（0〜10Hz)頻率正負交互 反轉的波形執行電解電鍍。 而當上述電解處理爲電解脫脂時，最好在含有氫氧化 鉀及/或氫氧化納的電解浴中，採用使100Hz〜1 kHz之頻率 正負交互反轉的波形，並以5V以下、0.5V以上的電壓來 執行電解脫脂。 -18- 200533788 (16) 〔實施例〕 接下來，利用實施例對本發明作更具體的說 ，本發明並不侷限於以下的實施例。 實施例1 採用第2圖所示的電解槽2 1，將以鋁合金製 構成要件的接合器鏈，配置在形成於分隔壁22 材插通部24，而形成鏈齒的側面及其周邊暴露於 ，並使來自於其他部分的電解液無法流通。 電解液採用1 %的硫酸，在接合器鏈的兩側 電極，並採用於交流中加入5 %直流成分的交直 形，且以頻率3kHz執行15V的定電壓電解。電 3 〇秒形成反轉，一邊使鏈移動於長軸方向一邊執 鐘的連續電解處理。其結果可平均地在鋁合金製 成厚度3 // m的陽極氧化皮膜。 實施例2 採用第2圖所示的電解槽2 1，並於長軸方向 1 〇條鋁合金製球鏈後放入形成於分隔壁22的被廣 通部2 4。 電解液採用5 %的硫酸，在球鏈的兩側配置一 ，並以頻率1 0 0 H z、1 0 V的定電壓執行交流電解。 以長軸方向的軸線作爲中心，使其一邊旋轉一邊朝 ，當然200533788 (1) IX. Description of the invention [Technical field to which the invention belongs] The present invention relates to: a continuous elongated member made of metal or alloy, or a continuous connection of a plurality of treated members made of metal or alloy as constituent elements Treated materials, such as metal, such as an adapter chain containing a metal or alloy sprocket and a stopper (upper stopper, lower stopper), and a continuously connected ball chain using a metal or alloy ball member as a constituent element Method and device for electrolytic treatment of to-be-processed material or alloy. [Previous technology] The general electrolytic treatment (anodic oxidation, electrolytic plating) is performed by treating the material to be surface treated as one of the electrodes and immersing it in the same electrolytic bath with the other electrode. Power is applied between the two. However, when a plurality of metal members are used as the material to be processed, for example, a large number of sprocket (rack) are fixed at a certain interval to the adapter chain of a zipper constituted by one end edge in the longitudinal direction of the adapter belt, In the case of a ball chain in which a large number of ball members are connected by a connection member such as a wire, it is difficult to perform the electrolytic treatment by the above-mentioned general method because the electrical connection cannot be formed between the members (for example, between adjacent sprocket elements). . Therefore, in the method for surface-treating the constituent members of the to-be-processed material composed of a plurality of metal members, the connector chain is wound around the outer periphery of a non-conductive cylindrical holder, and then the electric conductor wire is wound. Make contact around each metal sprocket (refer to Japanese Patent Volunteer Announcement: Sho 3 6-2 5 7); or wind the coupler chain around a conductive holder (see 200533788 (2) Voluntary announcement: Sho 3 6-1 1 8 7 1); or assembling the sprocket only to a conductive holding groove (see Japanese Patent Voluntary Sho ...-Sho 3 3-1 4 5 9) And perform the processing in a batch manner in a state where the metal splines are electrically connected. However, no matter which method is mentioned above, it is a method in which the electrode member (electrical conductor wire, conductive holder, or conductive holding groove) directly contacts the sprocket part and is energized. Contact is liable to cause inconsistencies, and it is easy to cause spot problems on a film formed by electrolytic treatment such as an anodized film. In addition, since all of the methods described above are batch-processed, productivity is not good. Therefore, a method is also performed in which a splicer chain is produced in a state where electrical connection is made between the sprockets in advance, and electrolytic processing is continuously performed on the splicer chain. For example, an adapter chain is produced by weaving a conductive wire into a fastener element assembly portion of a coupler generation in a state in which the teeth are electrically connected (see Japanese Patent No. 25 1 760). The connector chain of the conductive wire is continuously electrolyzed by forming a continuous conveyance through one side of the electrolytic bath by the guide roller of the guide roller (refer to Japanese Patent Laid-Open Publication: 2003-1193293). In the case of the above method, although the sprocket row can be simultaneously energized and the electrolytic treatment can be continuously performed, the conductive wire is expensive. In addition, because the conductive wire is made of metal, it is easy to cause conductivity during the production and dyeing process of the tape. There is a problem of poor productivity, such as wire breakage and metal melting. And other methods that are well known in the industry 'are to pre-assemble the fastener elements and stop members (upper stop, lower stop) of the zipper by methods such as roller plating, and -5- 200533788 (3) such as the ball chain Balls are plated on a plurality of minute components. However, in general drum plating, the current easily flows in the electrolytic solution, and it is difficult to sufficiently flow to the vicinity of the material to be treated. This not only has poor adhesion, but also has a problem that it is prone to staining. In addition, when the sprocket is electrolytically treated in advance, and it is fixed to the adapter belt to make an adapter chain, the cutting section shape is equivalent to the sprocket section compared to the general method of manufacturing an adapter chain. The method of simultaneously fixing a shaped wire (so-called Y-rod) to a belt part is complicated and time-consuming, resulting in high manufacturing costs. [Summary of the Invention] [Problems to be Solved by the Invention] The present invention is an invention that was developed in view of the problems of the above-mentioned conventional technology, and an object of the present invention is to provide a method including: (Upper stop, lower stop) adapter chains; and electrolytic connection of ball chains made of φ metal or alloy ball members as constituent elements to continuously connect them, which can solve the problem of direct contact of electrodes with metal or Inconsistencies in the processing of the treated components caused by the alloy, and can be processed without the use of conductive wires to form electrical connections to the sprocket rows, and can perform uniform plating treatment on the surface of the processed materials at low cost and efficiently Method and its device.

The material to be treated is arranged to separate the electrolyte, and a pair of separated electrodes are arranged on both sides of the material to be treated. Power is supplied to perform electrolytic processing. Regardless of which of the above-mentioned electrolytic treatment methods, the power supply method can be: positive or negative pair φ scale or positive and negative asymmetric waveform (AC, pulse waveform, saw waveform) Wait). A particularly suitable power supply method is a method of repeating one or two or more cycles. This cycle is to input the positive and negative symmetrical waveforms that alternately reverse the direct current, or the voltage or current, and then reverse the opposite poles of the input. power ups. As long as at least a part of the to-be-processed material is made of metal or alloy, all of them can be applied.

In addition, the electrolytic treatment method of the present invention solves surface modification methods such as plating, electrolytic honing, and electrolytic degreasing. Although the conditions of the electrolytic treatment can be appropriately set according to g, etc., when the material to be treated is a constituent element, and it is adhered to it, the direct current and the frequency below 10 k Η z and the voltage above 20 V are used. Electrolysis voltage is performed on the anode. In addition, when the above electrolysis treatment is an electrolytic bath that electrolyzes potassium oxide and / or sodium hydroxide, the waveforms of the frequency are alternately inverted to perform electricity. Furthermore, when the material to be processed contains copper The processing member is a constituent element, and it is preferable to perform electrolytic plating using a direct current and a frequency below 10 Hz. When the above electrolytic treatment is an electrolytic degreasing bath and / or sodium hydroxide electrolytic bath, the waveform of positive and negative reciprocal inversion is used, and the voltage is 5 V at a fat degree. According to the second feature of the present invention, it is an electrolytic solution of a solution treatment method. The processing device, the first piece (the upper stopper and / or the lower alloy ball member is used as a structure, is suitable for anodizing, electrically and electrically performing the material to be processed. The type and material of the material to be processed include aluminum or aluminum alloy. When it is anodized, the most positive and negative waveforms are reversed and oxidized. When honing, it is best to use honing at 5Hz to 200Hz when containing hydrogen. 丨-Zinc alloy, stainless steel and zinc perform electrolysis on it During electroplating, when the positive and negative waveforms are alternately reversed, it is best to perform electrolytic dehydration at a voltage containing a frequency of 100 Hz to 1 kHz containing hydrogen hydroxide. The characteristics that can perform the above electrical 1 well are: -8-200533788 ( 6) an electrolytic cell; and a partition wall configured to partition the electrolytic cell, the partition wall having an opening through which the electrolyte can flow, and a to-be-processed material insertion portion formed on the inner surface of the wall and crossing the opening. ;and A pair of electrodes arranged on both sides of the partition wall. The most suitable aspect is to arrange a leaky receiving tank under the above electrolytic cell, and between the electrolytic cell and the leaking receiving tank, the leakage can be arranged. The electrolyte in the liquid receiving tank is sent to the circulation line of the electrolytic cell. In addition, the second aspect of the electrolytic treatment device of the present invention is characterized by having: an electrolytic cell; and configured to separate the electrolytic cell, and is available for An electrically-insulating to-be-processed material accommodating tank through which an electrolyte flows; and a pair of electrodes separately disposed on both sides of the to-be-processed material accommodating tank. In a suitable aspect, the above-mentioned to-be-processed material accommodating tank is cylindrically porous The rotary drum is preferably formed with a plurality of protrusions on the inner surface of the porous rotary drum. [Effects of the Invention] According to the first aspect of the electrolytic treatment method of the present invention, since the φ-separated electrolyte is collected, only the Place the material to be treated in the electrolytic bath between the constituent elements of the material to be treated and / or the gaps around it, and place a pair of separated electrodes on both sides of the material to be treated , The electrode is supplied with electricity to perform the electrolytic treatment, so that the current can easily pass near the interface between the material to be processed and the electrolyte. Therefore, the electrolytic treatment can be made more efficient to perform a consistent electrolytic treatment, and the concentration of the electrolytic bath can be more traditional The electrolytic treatment is lower. In addition, when performing anodizing treatment or electrolytic plating of the connector chain or ball chain, it is not necessary to use materials as expensive as conductive wires, and only needs to add processing steps to the traditional steps to perform efficiently. -9 -The electrolytic treatment of 200533788 (7) can form a film with consistent color, excellent durability and corrosion resistance, and provide adapter chains and ball chains with various decorative properties. In addition, the material to be processed is moved by one side While performing continuous electrolytic treatment, it is possible to perform electrolytic treatment with high productivity and low cost. According to the second aspect of the electrolytic treatment method of the present invention, the material to be processed is arranged to separate the electrolytic bath and is accommodated in the electrolytic solution. The electrolytic treatment is performed in a state where the electrically insulating material to be processed can be circulated. Although it is a batch process, it is essentially Only the material from the space between the processing and circulation of the electrolyte around the slot being received treatment material, even in the above case, the current can easily through the vicinity of the interface between the material and the electrolyte is treated. Therefore, the electrolytic treatment can be made more efficient to perform a consistent electrolytic treatment, and the concentration of the electrolytic bath can be lower than that of the conventional electrolytic treatment. In addition, when anodizing treatment or electrolytic plating is performed on small metal or alloy processed members such as the chain teeth of the adapter chain, ball members of the ball chain, push buttons, rivets, etc., it can form a uniform color and has excellent durability. And corrosion-resistant coating. According to the first aspect of the electrolytic treatment device of the present invention, it is possible to perform production on continuous elongated members made of metal or alloy, or a plurality of processed members made of metal or alloy as continuously connected processed materials constituting elements. Good performance and low cost electrolytic treatment. In addition, according to the configuration of a leaky receiving tank disposed below the electrolytic cell, and between the electrolytic cell and the leaking receiving tank, a suitable form of a circulation line capable of sending the electrolyte in the leaky receiving tank to the electrolytic cell is provided. 'Electrolyte can be used efficiently and the burden on waste liquid disposal can be reduced. According to the second aspect of the electrolytic treatment apparatus of the present invention, although the batch process is formed, the electrolytic process can be made more efficient to perform a consistent electrolytic process -10- 200533788 (8). In addition, in a state where the to-be-processed material storage tank is a cylindrical porous rotary drum 'and the inner surface of the porous rotary drum is preferably formed with a plurality of protrusions,' it is capable of efficiently agitating and storing in the to-be-processed material storage. The agitating means (the above-mentioned protrusion) of the material to be processed in the tank can further improve the consistency of the electrolytic treatment. [Embodiment] p As described above, the electrolytic treatment method and device of the present invention do not contact the electrode with the member to be treated, nor use special materials such as conductive wires, but use the method of power supply in the electrolytic bath to perform the electrolytic treatment. Only the electrolyte from the gaps between the members to be treated and the surroundings are circulated, and the current can easily pass near the interface between the members to be treated and the electrolyte. In this way, consistent electrolytic treatment can be performed, and in addition, the concentration of the electrolytic bath can be lower than that of the conventional electrolytic treatment. The first aspect of the so-called means to circulate the electrolytic φ liquid from the gap between the members to be treated and its surroundings is to separate the electrolyte, and only make up the constituent elements from the material to be treated that should be treated substantially. The to-be-processed material is arrange | positioned in the electrolytic bath so that the electrolyte solution in the gap in and / or around it may circulate. In addition, the second aspect is a place in which only the electrolyte from the gaps between the materials to be processed and its surroundings is circulated, and the materials to be processed formed by or including the plurality of processed members are housed in An electrically insulating to-be-processed material accommodating tank through which an electrolytic solution can flow is arranged to separate the electrolytic solution. In the following, the best embodiment of the present invention shown in the drawings will be described -11-200533788 (9), and the present invention will be described in detail. However, the present invention is not limited to the following embodiments. First, Figures 2 to 4 show examples of processing materials that are suitable for continuous elongated members made of metal or alloy, or a plurality of processed members made of metal or alloy that are continuously connected as constituent elements. For example, an adapter chain including a metal or alloy sprocket and a stopper (upper stopper, lower stopper), and a continuous g-linked ball chain having a metal or alloy ball member as a constituent element are used as An example of an electrolytic treatment device for a material to be processed and a wire (a so-called Y rod) having a cross-sectional shape corresponding to a sprocket cross-sectional shape. A schematic diagram of a representative example, that is, one example of a zipper is shown in FIG. 1. As shown in FIG. 1, the adapter chain 1 is composed of: an adapter belt 2 with a core portion 3 formed on one of the edge sides thereof; and a core portion 3 riveted and fixed (fixed) to the adapter belt 2 at a certain interval. The upper teeth 5 (sprocket) 4 and the upper teeth 5 and the lower teeth 6 are further riveted and fixed to the core 3 of the adapter belt. The zipper is composed of: a pair of φ adapter chains 1 forming a confrontation with each other; and a slider 7 which is arranged between the above-mentioned sprocket 4 and can slide freely in the up-down direction, and is used to perform the engagement and separation between the sprocket. In addition, the type of the sprocket 4 fixed to the core portion 3 of the adapter belt 2 has various types other than the content of the drawing in addition to the coil-shaped sprocket, and any of the above can be applied.于 发明。 In the present invention. Fig. 2 shows a schematic structure of the main body of the electrolytic device. The electrolytic cell 2 of the electrolytic treatment device 20 is divided into two parts by a partition wall 22. The partition wall 22 includes: an opening portion 23 through which the electrolyte can flow; and a -12-200533788 (10) treated material which is formed in the partition plate 2 2 and cuts through the opening portion 23 in a slightly vertical direction.插 通 部 24。 The insertion portion 24. The example shown in the figure is an example in which the side walls of two tanks are joined to form one electrolytic cell. In other words, the openings are penetrated in advance at the relative positions of the side walls of the two grooves, and the openings 23 are formed when the two side walls are joined. In addition, the grooves are formed in the vertical direction of the opposing portions of the two side walls in advance. A partition wall 22 is formed when the two side walls are joined, and a to-be-processed material insertion portion 24 is formed between the partition walls. The present invention is not limited to the above-mentioned manufacturing method, and a partition wall 22 in which an opening 23 and a to-be-processed material insertion portion 24 crossing the opening 23 are formed in advance may be arranged in one electrolytic cell 21 to It is divided into two tank chambers. Further, the electrodes 25a and 25b are respectively arranged in the tank chambers on both sides of the partition plate 22, and the electrodes 25a and 25b are connected to the power source 26. The size of the electrodes 2 5a and 25b is preferably larger than the size of the opening 23, and the position can be arbitrarily set, as long as the electrodes 2 5 a are separated from both sides of the partition wall 2 and face each other. It is sufficient that the projection area of 2 5 b covers the position of the opening 23. In addition, as shown in FIG. 3, a leakage receiving tank 27 is arranged below the electrolytic tank 21, and a circulation line 28 is provided between the leakage receiving tank 27 and the electrolytic tank 21, and the leakage receiving tank The electrolytic solution L in 27 is sent to the electrolytic cell 21 by the pump 29. The size (width and depth) of the to-be-processed material insertion portion 24 formed in the partition wall 22 is set to be larger than the width and thickness of the to-be-processed material. In addition, the size of the opening 23 may correspond to the size of the to-be-processed material. Make the appropriate settings. For example, when the material to be processed is an adapter chain 1 and the component to be processed is a chain-13- 200533788 (11) Tooth 4, the width of the opening 23 is set in a state where a pair of adapter chains are engaged. A size slightly equal to the total width of the sprocket teeth 4 on both sides or slightly larger than the above-mentioned total width. By setting the dimensions described above, only the sprocket 4 of the adapter chain 1 to be actually treated can be immersed in the electrolytic solution, so the amount of the electrolytic solution taken out after penetrating into the adapter belt 2 can be suppressed to As a minimum, deterioration of the adapter belt 2 can also be prevented. In the electrolytic treatment, since only the electrolyte that actually comes from the sprocket 4 (the member to be treated) and / or the gap between the sprocket 4 flows, an electric current can easily pass near the interface between the sprocket and the electrolyte. Therefore, the electrolytic treatment can be made efficient, and a consistent electrolytic treatment can be performed. During the electrolytic treatment, as shown by the arrows in Figs. 3 and 4, the adapter chain inserted into the to-be-processed material insertion portion 24 is sequentially carried downward while the electrolytic treatment is continuously performed. At this time, although the electrolytic solution L leaked from the opening at the lower end of the to-be-processed material insertion portion 24, it was collected in the leaky receiving tank 27 below. The electrolytic solution L concentrated in the leaky receiving tank 27 is sent to the above-mentioned electrolytic tank 21 by a pump 29. In the above-mentioned aspect, 'the leaky receiving tank 27 is arranged below the electrolytic tank 21, but the inner tank (equivalent to the electrolytic tank) may be arranged in the outer tank (equivalent to the leaking receiving tank). Inside, the adapter chain carried out from the opening at the lower end of the to-be-processed material insertion portion of the inner tank (electrolytic cell) is conveyed while being guided upward between the inner tank and the outer tank by a guide roller. In the above case, since the inner tank and the outer tank communicate with each other through the lower opening of the to-be-processed material insertion portion, the liquid level of the electrolyte is the same as the inner tank and the outer tank. Therefore, the above-mentioned pump 29 is unnecessary. ° -14- 200533788 (12) The electrolytic treatment method of the present invention is based on the power supply in the electrolytic bath. Here is an example of anodization. For example, the power supply powers the two electrodes 25a and 25b. The electrode is an anode, and the other electrode 25b is a cathode. The surface of the sprocket 4th 25a side is negatively charged, and the surface of the electrode 25b side is positively oxidized to form an anodized film. Conversely, the electrode 2 5 a is used as the cathode, and the other electrode 2 5 b is used as the anode sprocket 4 The surface on the electrode 2 5 a side is positively charged, and the surface on the electrode 2 5 b is negatively charged, so that the surface on the electrode 25a side is After oxidation, an anode film is formed. In this way, an anode film can be formed on the entire surface of the sprocket 4. The principle of power supply in this electrolytic bath is not limited to anodic oxidation. It is all methods applicable to the surface modification of electrical materials such as electrolytic plating, electrolytic honing, and electrolytic degreasing. Figures 5 and 6 show an example of a square chain to which the electrolytic treatment of the present invention is applied. This ball chain 30 has a structure in which a plurality of metal or alloy hollow spherical balls 31 are used as the connecting member 3 2. When the electrolytic device 20 performs electrolytic treatment on the ball chain 30, the chain is formed to have a width that is slightly equal to the width of the opening 23, and then passes through the material 24 to be processed downward while being carried downward. In the electrolytic treatment, only the electrolyte that substantially comes from the gap around the ball chain treatment material and / or between the balls 31 can flow through the electrolytic solution, and can easily pass near the interface between the ball chain 30 and the electrolyte. Therefore, the electrolytic treatment becomes efficient, and a consistent electrolytic treatment can be performed. When electrolytic treatment is performed on a wire such as a Y rod, the method of the opening part is to use DC 25a as an electrode to make electricity. If the side surface oxide scale is treated, the ball connection of the treatment is reused. The field described by several ball insertion parts 30 (the current is able to make 23-15-15-200533788 (13) The size only needs to be set: the Y rod and the opening part 2 located in the insertion part 2 4 of the material to be processed The size of three gaps through which the electrolyte can flow is sufficient. In addition, when performing the electrolytic treatment on the linear object to be processed, a more suitable electrolytic process can be performed by rotating the object to be transported. Figures 7 and 8 show components made of small metals or alloys such as the sprocket 4 of the adapter chain 1, the ball 31 of the ball chain 30, or push buttons, rivets, etc. One of the electrolytic treatment devices of the present invention is an example of the electrolytic treatment device of the present invention. In the electrolytic treatment device 20, the electrolytic cell 21 is divided into two tank chambers by a partition wall 22 having an opening portion 23, and an electrolytic solution is available therefor. Circulating cylindrical electrical insulation blanket The physical material accommodating tank 40 is rotatably arranged at the opening 23 with the rotation axis 41 as the center. The material accommodating tank 40 is a cylindrical porous rotary drum having an outer peripheral wall and an inner peripheral wall. It is mesh-shaped to allow the electrolyte to circulate. In addition, the outer peripheral wall and the inner peripheral wall can also be formed of perforated plates. On the inner peripheral surface of the to-be-processed material accommodating tank 40, a plurality of φ protrusions are formed substantially throughout the entire length. (Strip) 42. In the same manner as the above-mentioned embodiment, a pair of electrodes 25a and 25b separated from each other are arranged on both sides of the material receiving tank 40, and the pair of electrodes is connected to a power source 26. In the electrolytic treatment device 20 having the above structure, it is preferable to adjust the liquid surface height of the electrolytic solution L to be slightly equal to the height of the entire to-be-processed material 10 in the to-be-processed material accommodating tank 40 that undergoes rotation during electrolytic processing. Since only the electrolyte that substantially flows from the space between the members to be treated and the surrounding space can flow, the current can easily pass near the interface between the member to be treated and the electrolyte. In this way, the electrolytic treatment can be made efficient , It can also perform electrolytic treatment of -16- 200533788 (14). In addition, since a plurality of protrusions (protrusions) 42 are formed on the inner surface of the processing material accommodating tank 40, it can be efficiently stirred and stored in the processing target. The processed components in the material storage tank 40 can further improve the consistency of the electrolytic treatment. Regardless of which of the above-mentioned electrolytic treatment methods, the power supply method can be used to reverse the direct current, or the voltage or current alternately positive and negative Positive or negative symmetrical or positive and negative asymmetric waveforms (AC, pulsed waveform, saw-shaped waveform, etc.). The most suitable power supply method is to repeat the cycle 1 or more times. This cycle is used to make the DC, Positive or negative symmetrical waveform of alternating voltage or current reversed for a certain period of time, the method of inverting the input counter electrode and energizing it. Examples of several waveforms are shown in Figures 9 and 10. Figure 9 (A) shows a DC waveform, (B) ~ (D) are positive and negative symmetrical waveforms, where (B) is an AC waveform, (C) is a pulse waveform, (D) is a saw-shaped waveform, and (E ) Is a pulse asymmetric waveform. In addition, Fig. 10 shows an alternating-current asymmetric waveform, which is a waveform in which the negative absolute I pair 値 is larger than positive absolute 値 (a) and the negative absolute 値 is smaller than positive absolute 値 (b). . By applying one of the positive and negative asymmetric waveforms described above for a certain period of time, and repeating the energization cycle in which positive and negative are alternately applied to each other, it is possible to sufficiently penetrate the sprocket meshing portion to perform electrolytic treatment. In addition, the electrolytic treatment method of the present invention is applicable to one or two kinds of mineral or organic acids containing sulfuric acid, chromic acid, phosphoric acid, oxalic acid, malonic acid, maleic acid, and aminosulfonic acid. The anode in the above acidic aqueous solution is subjected to electrolytic treatment to form an anodic oxide film, or the acidic containing sulphuric acid and phosphoric acid is used to form an anodic oxide film. 17-200533788 (15) Electrolytic bath, neutral electrolytic bath containing fluoric acid, etc. Oxidation treatment; or electrolytic plating (electrodeposition) in an electrolytic solution containing metal ions or metal compound ions such as nickel, chromium, gold, and silver; electrolysis in alkaline aqueous solutions such as potassium hydroxide and sodium hydroxide All methods of surface modification of the electrically treated material, such as electrolytic honing or electrolytic degreasing. Since the above-mentioned processing methods are well known in the industry, their descriptions are omitted. Although the conditions of the electrolytic treatment can be appropriately set depending on the type and material of the material to be processed, when the material to be processed contains aluminum or aluminum alloy as a constituent element, and anodizing treatment is performed on it, It is good to use a waveform that reverses the positive and negative of DC and frequency below 10kHz (0 ~ 10kHz), and performs anodizing treatment with an electrolytic voltage above 20V and below 50V. In addition, when the above-mentioned electrolytic treatment is electrolytic honing, it is preferable to perform the electrolytic honing in a electrolytic bath containing potassium hydroxide and / or sodium hydroxide by using a waveform in which the frequency of 5 Hz to 200 Hz is alternately reversed. Furthermore, when the material to be processed contains copper-zinc alloy, stainless steel, and zinc to-be-processed members as constituent elements, and electrolytic plating is performed thereon, it is preferable to use direct current and a frequency below 10 Hz (0 to 10 Hz). The alternately inverted waveform performs electrolytic plating. When the above-mentioned electrolytic treatment is electrolytic degreasing, it is best to use a waveform in which the frequency of 100 Hz to 1 kHz is alternately inverted between positive and negative in an electrolytic bath containing potassium hydroxide and / or sodium hydroxide, and the voltage is less than 5V and 0.5V. Above the voltage to perform electrolytic degreasing. -18- 200533788 (16) [Examples] Next, the present invention will be described more specifically using examples. The present invention is not limited to the following examples. Example 1 An electrolytic cell 21 shown in FIG. 2 was used, and an adapter chain made of an aluminum alloy was arranged on a material insertion portion 24 formed in a partition wall 22, and the side surfaces forming the sprocket and its periphery were exposed. As a result, the electrolyte from other parts cannot flow. The electrolyte uses 1% sulfuric acid, electrodes on both sides of the adapter chain, and an AC-DC shape with 5% DC component added to the AC, and performs a constant voltage electrolysis of 15V at a frequency of 3kHz. A continuous electrolytic process in which the electric current is reversed in 30 seconds and the bell is clocked while moving the chain in the long axis direction. As a result, an anodized film having a thickness of 3 // m can be formed on the aluminum alloy on average.

As a result, an anodized film having a thickness of 1 // m can be formed on the aluminum alloy ball chain evenly. Embodiment 3 An electrolytic cell 21 shown in FIG. 7 is used, and a porous cylindrical rotary drum made of an acid-resistant resin having a plurality of fine pores is used to smoothly circulate the electrolytic solution. The partition wall 22 of the two tank chambers has 23 openings | 23 openings, so that the electrolyte other than the drum cannot flow, and a plurality of splicing elements made of aluminum alloy are put into the drum until about 1/4 of the drum is formed. Then, the electrolyte is injected into the electrolytic cell to form a position slightly equal to the height of the sprocket when the drum rotates. The electrolyte uses 1% sulfuric acid, and while rotating the drum, it performs AC electrolysis at a constant voltage of 1 kHz and 35 V for 60 minutes. As a result, an anodic oxide film having a thickness of 3 // m can be formed on the sprocket made of aluminum alloy on average.
