本発明は、ばね台材に取付けて摺動接点として
使用する櫛歯状の摺動用刷子を作る刷子材料の改

従来、この種刷子材料には、Cu−Be，Cu−
Ni，Cu−Sn，Cu−Ni−Zn，Cu−Ti，PBS等の
Cu基合金が用いられてきたが、これ等のCu基合

た摩耗粉によりノイズが発生するものである。 Conventionally, this seed brush material includes Cu-Be, Cu-
Ni, Cu-Sn, Cu-Ni-Zn, Cu-Ti, PBS, etc.
Cu-based alloys have been used, but if a comb-shaped sliding brush made of these Cu-based alloys is attached to a spring base and used as a sliding contact in contact with a commutator, the commutator will rotate. When the sliding contact slides, the contact part of the comb-shaped sliding brush is significantly worn out due to electrical and mechanical erosion, resulting in a short service life. Further, noise is generated due to wear particles.
本発明は斯かる問題を解決すべくなされたもの
であり、電気的，機械的侵蝕による摩耗が極めて
少ない安定した櫛歯状の摺動用刷子を作ることの

である。 The present invention has been made to solve this problem, and provides a brush material for sliding contacts that can produce a stable comb-shaped sliding brush with extremely little wear due to electrical and mechanical erosion. That is.
本発明の摺動接点用刷子材料は、Cu基合金の
表面に３層の被覆が施され、第１層はCr，Ni，
Ni合金，Reのいずれかが厚さ0.1〜10μｍ、第２
層はRh，Pt，Pd，Ruのいずれかが厚さ0.1〜10μ
ｍ、第３層はAu，Ag，Au−Agのいずれかが厚
さ0.1〜10μｍの被覆であることを特徴とするもの
である。 The brush material for sliding contacts of the present invention has a three-layer coating applied to the surface of a Cu-based alloy, and the first layer is made of Cr, Ni,
Either Ni alloy or Re has a thickness of 0.1 to 10 μm, and the second
The layer is Rh, Pt, Pd, or Ru with a thickness of 0.1 to 10μ.
m, the third layer is characterized by being a coating of Au, Ag, or Au-Ag with a thickness of 0.1 to 10 μm.

のいずれかを厚さ0.1〜10μｍ被覆した理由は、第
２層の表面を化学的に安定させて電気的侵蝕を防

で、厚さ0.1μｍ未満ではその効果が無く、厚さ
10μｍを超えても化学的安定度が格別に向上する
ものではなく、10μｍ未満で充分初期溶着を防止
できるものである。 In this way, Cr is added as the first layer on the surface of Cu-based alloy.
The reason for coating Ni, Ni alloy, or Re with a thickness of 0.1 to 10 μm is to impart mechanical hardness to the Cu-based alloy brush material and improve wear resistance during sliding. If the thickness is less than 0.1 μm, there is no effect, and the thickness
This is because if the thickness exceeds 10 μm, the spring properties will be reduced and the commutator, which is the other party during sliding, will wear out more quickly. Further, as a second layer, Rh, Pt, Pd,
The reason for coating Ru with a thickness of 0.1 to 10 μm is to provide mechanical hardness and at the same time chemically stabilize the surface of the first layer, improving wear resistance during sliding. This is to prevent electrical corrosion, and if the thickness is less than 0.1 μm, it will not be effective, and if the thickness exceeds 10 μm, the springiness will decrease and the commutator, which is the other party during sliding, will only be worn out faster, and it will cause chemical damage. This is because stability is not particularly improved. Furthermore, the third
Au, Ag, Au-Ag on the surface of the second layer as a layer.
The reason for coating either of them with a thickness of 0.1 to 10 μm is to chemically stabilize the surface of the second layer and prevent electrical corrosion, as well as to prevent initial welding after the start of sliding. There is no effect if the thickness is less than
If the thickness exceeds 10 μm, the chemical stability will not be particularly improved, and if the thickness is less than 10 μm, initial welding can be sufficiently prevented.
