Description
異なる数種のニッケル系鑞材が、米国溶接協会(American Welding Society)規格(ANSI/AWS A 5.8)に列挙されている。こうしたニッケル系鑞材のうちの多数が、熱交換器を鑞付けするために使用される。Ni−7Cr−3B−4.5Si−3Feという組成を有するBNi−2が、高温用途において高強度接合部を形成するために使用されるが、ホウ素を含有することが欠点である。その理由は、ホウ素が基材内に拡散した場合、基材の脆化を引き起こす虞があるからである。他のホウ素を含むニッケル系鑞材も同じ欠点を有する。
この鑞材の典型的な使用は、腐食環境で動作する高温用途である。こうした用途は、自動車用途、例えば、排ガス再循環で使用される多様な型の熱交換器(板状又はパイプ状)でありうる。他の実例は、多様な型の触媒コンバータである。
少なくとも20重量%の鉄、
約2〜20重量%、好ましくは、5〜15重量%の銅、
約11〜35重量%、好ましくは、20〜30重量%のクロム、
約0〜30重量%、好ましくは、10〜20重量%のニッケル、
約2〜10重量%のケイ素、
約4〜10重量%のリンであり、
ケイ素が6重量%以下の場合には、リンは8重量%超であり、
リンが8重量%以下の場合には、ケイ素は6重量%超である。これは、
ケイ素含有量が6重量%超かリン含有量が8重量%超かのいずれかであるか、又は
その両方、即ち、Si含有量が6重量%超かつP含有量が8重量%超であること
を意味する。
Fe24Cr20Ni10Cu7P5Si5Mn(参考材料1と呼ぶ)及びFe29Cr18Ni7Si6P(参考材料2と呼ぶ)である。
鑞材(0.2グラム)をステンレス鋼基材の中心に直径9mmの円形に置いた。粉末で覆われた領域、すなわち元の粉末領域(Ai)は63.6mm2であった。次いで鑞材が置かれた基材を10−4Torrの真空下で1100℃で30分間加熱した。濡れ性をS=Am/Aiにより定義される拡がり比で求めた。上式中、Amは溶融鑞材の領域であり、Aiは元の粉末領域である。
金属粉末を結合剤と混合することによって鑞材をペーストに転換した。ステンレス鋼304を基材として使用した。図1によるT供試体を10−4Torrの真空下で1100℃で30分間鑞付けした。鑞付け後、T供試体を切断して、鑞付け接合部の断面領域を光学顕微鏡で検査した。良好な鑞付け接合部が、均一な微細組織を有する孔及び亀裂のない接合部であると同定された。
100μmの平行クリアランスを有するラップ型接合構造についてANSI/AWS C3.2M/C3.2.2001で勧奨されたものと類似の手順を使用して接合部の強度を試験した(図2を参照されたい)。鑞付けする前に、鑞材を結合剤と混合することによって鑞材をペーストに転換した。次いで、ペーストを付与した接合部の強度用供試体を10−4Torrの真空下で1100℃で30分間加熱した。
腐食媒体を入れたビーカー内に鑞付けしたT供試体を1週間浸漬することによって耐食性を調査した。その後に供試体の腐食の徴候を検査した。それぞれの合金につき1つ、合計で5つの鑞付けされた供試体を作製した。用いた腐食媒体は10重量%のH2S04水溶液であった。
