In particular, adhesion wear is remarkable in the conventional silver or silver alloy plating finish. Since the silver or silver alloy of the present invention has a release of internal stress, it has the feature that adhesive wear is less likely to occur compared to conventional products. However, this coating alone cannot provide a sufficient effect. In combination with gold, a gold alloy, palladium, a palladium alloy, platinum, a platinum alloy, rhodium, or a rhodium alloy, a great effect is exhibited.
- silver or a silver alloy may prevent sulfur discoloration during motor sliding or stopping. This prevents an increase in contact resistance due to discoloration caused by contact of grease or sulfur components in the atmosphere with silver or a silver alloy around the commutator, and a longer life is expected.

For this reason, by forming the outermost layer made of the above elements, the outermost surface layer can be recovered, and the outermost layer can be improved in the life of the motor.
- the silver or silver alloy of the present invention As a base of the silver or silver alloy of the present invention, one or more layers of nickel or cobalt and their alloys can be coated.
- This base plating acts as a diffusion barrier for the substrate, and has an effect of preventing the substrate component from diffusing in the silver or silver alloy layer to reach the surface layer and increasing the contact resistance.
- the thickness is not limited, but is applied in the range of 0.1 to 2.0 ⁇ m.
- the surface reduction processing performed after coating with silver or a silver alloy is performed using a rolling mill, and the surface roughness (arithmetic average roughness) of the rolling roll at that time is adjusted to Ra of 0.2 ⁇ m or less.
- the surface-reducing process of the present invention releases the internal stress of silver and silver alloy and reduces the surface roughness, and further, the substrate and silver or silver alloy layer, or the underlayer and silver or silver.
- the purpose is to increase the bond strength with the alloy layer and improve the adhesion.
- the surface-reducing process is performed by rolling, but the silver and the silver alloy coating are recrystallized due to plastic deformation during the rolling and the accompanying heat generation, the internal stress is released, and the coating is hard to adhere to wear.
- the surface roughness of the work roll used in the rolling process can be reduced, and an effect that adhesion wear is less likely to occur is exhibited. Furthermore, the interfacial bonding force between the substrate and the silver or silver alloy layer, or the base layer and the silver or silver alloy layer is improved by mechanical force and plastic working force, providing a film with even better adhesion. can do.
- the area reduction rate is preferably in the range of 1 to 80%, more preferably 5 to 50%.

The effect is recognized when the surface roughness of the work roll for rolling is Ra 0.2 ⁇ m or less, and preferably 0.1 ⁇ m or less.
- the width of the stripe and the interval between the stripes are adjusted appropriately.
- the stripe width is the minimum necessary width that contacts the brush of the micromotor, and is generally about 1 to 10 mm.
- the width of the commutator material is often about 8 to 30 mm, and 10 to 30% of the width is covered with striped silver or a silver alloy.
- the outermost layer made of gold, gold alloy, palladium, palladium alloy, platinum, platinum alloy, rhodium, or rhodium alloy is formed by plating to recover the decrease in surface cleanliness due to surface reduction.
- the source of contaminants such as rolling oil, so that the effect of suppressing the reduction in motor life can be obtained.
- the plating at the product width causes the plating thickness distribution to occur in the product width direction, resulting in deterioration of the plate thickness accuracy, greatly affecting the roundness when molded into a motor commutator, and brush vibration during motor rotation.
- This causes problems such as a decrease in life, followability, and mechanical and electrical noise.
- This problem is remarkable when the plating thickness is 1 ⁇ m or more, and this problem has been solved by the present invention.
- the plating cost can be significantly reduced by performing silver or silver alloy plating several times as wide as the product width and then slitting the product into the product width.

Abstract
Description
整流子用材料に使用されているCu合金基材は、板厚が0.1~0.3mmの純Cu系、Cu-Sn系、Cu-Sn系が多く、Ag合金としては、Ag-Mg系、Ag-Cu系、Ag-Ni系が多い。Ag合金の被覆は、ブラシと接触する部分にのみ被覆したインレイ材が一般的で、被覆厚は通常20~100μmである。
(1)AgやPdなどの貴金属の被覆率が大きいため、コストが高い。
(2)クラッド法で製造しているため、製造コストが高い。
(3)クラッドは焼鈍と圧延を繰り返して製造するため、Ag合金表面は加工による加工変形層が生成し、耐アーク性に劣り整流子およびブラシの磨耗が早くモータ寿命が短い。
(4)クラッドは焼鈍と圧延を繰り返して製造するため、Ag合金の表面にはAg以外の合金成分が濃化おり初期の接触抵抗が高く、耐食性にも劣る。
(5)Ag合金部と半田めっき部以外の部分は基材が露出しており、Cu合金基材は耐食性が悪いために変色や、更に進行すると腐食生成物のクリープ現象による接点部の汚染が発生する。
これらの問題を解決するため、Ag合金組成の開発や、Ag合金皮膜上へのAuおよびAu合金の被覆等が行われてきたが、一部の問題点の解決にしかならず、総合的な改善を望まれていた。
ストライプ状に貴金属をめっきで被覆した場合、クラッドに比べて大幅に安価になるものの、めっき被膜はその組織が緻密で、かつ内部応力が大きいためにブラシとの摺動時に凝着摩耗が発生して整流子の貴金属が大きく損傷し、期待したモータ寿命が得られないのが現状である。
また、ストライプめっきは、製品幅で施すために、めっき加工費が比較的高くなるのが現状である。
(1)導電性基体の全面または一部に銀または銀合金を被覆し、更に銀または銀合金の表面に金、金合金、パラジウム、パラジウム合金、白金、白金合金、ロジウム、ロジウム合金のうち、いずれかからなる最表層を被覆した材料であって、導電性基体に銀または銀合金を被覆した後、減面加工を施し、その後に部分的に金、金合金、パラジウム、パラジウム合金、白金、白金合金、ロジウム、ロジウム合金のうち、いずれかからなる最表層を被覆したことを特徴とする、整流子材料。
(2)導電性基体と銀または銀合金の中間層との間にニッケルまたはニッケル合金、コバルトまたはコバルト合金のうち、いずれかを1層以上を被覆したことを特徴とする(1)記載の整流子材料。
(3)導電性基体の全面または一部に銀または銀合金を被覆した後の減面加工が、ロール表面における算術平均粗さRaが0.2μm以下のワークロールを用いた圧延機で施されていることを特徴とする(1)または(2)記載の整流子材料。
(4)導電性基体の全面または一部に銀または銀合金をめっき行い、次いで、ロール表面における算術平均粗さRaが0.2μm以下のワークロールを用いた圧延機で減面加工を行い、その後部分的に金、金合金、パラジウム、パラジウム合金、白金、白金合金、ロジウム、ロジウム合金のうちいずれかをめっきすることで最表層を形成することを特徴とする整流子材料の製造方法。
(5)前記の(1)~(3)のいずれか1項の整流子材料を整流子に用いたことを特徴とするマイクロモータ。
本発明で導電性基体の全面または一部に銀または銀合金を被覆する場合の、一部とは、マイクロモータのブラシと接触する最低限必要な幅であり、一般的には1~10mm程度である。また、整流子用材料の幅は8~30mm程度が多く、この幅に対して10~30%の部分にストライプ状の銀または銀合金が被覆される。
図1(1)に示すように、基体4の一面(表面)上に、めっきの下地層となるニッケル、ニッケル合金、コバルト、コバルト合金のうちいずれかからなる層3を介して銀または銀合金層2が形成され、さらに例えば部分的な被覆形状であるストライプ状の金、金合金、パラジウム、パラジウム合金、白金、白金合金、ロジウム、ロジウム合金のうちいずれかからなる最表層1が形成されている構成である。
図1(2)に示すように、基体4の一面(表面)上に、銀または銀合金層2が形成され、さらに例えば部分的な被覆形状であるストライプ状の金、金合金、パラジウム、パラジウム合金、白金、白金合金、ロジウム、ロジウム合金のうちいずれかからなる最表層1が形成されている構成である。
図1(3)に示すように、基体4の一面(表面)上に、銀または銀合金層2が形成され、さらに例えば部分的な被覆形状であるストライプ状の金、金合金、パラジウム、パラジウム合金、白金、白金合金、ロジウム、ロジウム合金のうちいずれかからなる最表層1が形成されていて、基体4の裏面に銀または銀合金層2が形成されている構成である。
図1(4)に示すように、基体4の一面(表面)上に、めっきの下地層となるニッケル、コバルト、またはこれらの合金からなる下地層3を介して銀または銀合金層2が形成され、さらに例えば部分的な被覆形状であるストライプ状の金、金合金、パラジウム、パラジウム合金、白金、白金合金、ロジウム、ロジウム合金のうちいずれかからなる最表層1が形成されていて、基体4の裏面にめっきの下地層となるニッケル、ニッケル合金、コバルト、コバルト合金のうちいずれかからなる層3を介してAgまたはAg合金層2が形成されている構成である。
本発明の減面加工は、銀および銀合金のめっき内部応力を開放すること、および、表面粗度を小さくすること、さらには基材と銀または銀合金層、または、下地層と銀または銀合金層との結合力を高め、密着性を向上させることを目的としている。減面加工は圧延によって行うが、圧延時の塑性変形とそれに伴う発熱によって、銀および銀合金被膜が再結晶して内部応力が開放され、凝着摩耗しづらい被膜に変化する。また、圧延加工で使用するワークロールの表面粗度を小さくすることで、銀および銀合金の表面粗度を小さくすることができ、凝着摩耗がさらに発生しづらくなる効果が発現する。さらには基材と銀または銀合金層、または、下地層と銀または銀合金層との界面結合力を、機械的な力、塑性加工力により向上させ、より一層密着性に優れた皮膜を提供することができる。減面加工率は、好ましくは1~80%の範囲で行われ、より好ましくは5~50%である。減面加工率が1%未満では銀および銀合金の再結晶が不充分であり、80%を越えると効果が飽和してしまう。圧延のワークロールの表面粗度はRa0.2μm以下で効果が認められ、好ましくは0.1μm以下である。
銀または銀合金めっき後に減面加工を施すことにより、めっきで出来た凸部を平滑にすることができ結果的に板厚精度が向上する。また、銀または銀合金のめっきを製品幅の数倍の広幅で施し、次いで、製品幅にスリット加工することでめっき加工費を大幅に低減することが可能になる。
連続的に条材にめっきを施すラインにおいて、表1に示した板幅100mm、板厚は各種のサイズのC14410条(基体)を通板して、電解脱脂、酸洗の前処理を行った後、めっきを施し、更に、圧延加工を行った。その後、スリッターで幅30mmに切断して、金、金合金、パラジウム、パラジウム合金、白金またはロジウムを幅5mmにストライプめっきを施して本発明の整流子材料を得た。
上記の整流子材料をプレス加工し、マイクロモータに組み込んでモータ寿命の試験を行った。尚、ブラシ材にはめっき厚さ1μmのPdめっきを施したバネ用洋白条(C7701R-H材)0.07mm厚を用いた。
