Summary: | PROBLEM TO BE SOLVED: To provide a silver coated material with a surface having a small coefficient of dynamic friction.SOLUTION: The silver coated material comprises a metallic substrate 1 and a silver coating film 2 composed of silver or silver alloy and coating a surface 1a of the metallic substrate 1. The silver coating film 2 is arranged on an outermost surface of the silver coated material. A plurality of granular projections 2b are formed on a surface 2a of the silver coating film 2, the surface 2a of the silver coating film 2 has an average spacing of local peaks of 0.3 μm to 3.0 μm and a ten point average roughness Rz of 0.3 μm to 10.0 μm.SELECTED DRAWING: Figure 1
【課題】表面の動摩擦係数が小さい銀被覆材料を提供する。【解決手段】銀被覆材料は、金属製基材1と、銀又は銀合金からなり金属製基材1の表面1aを被覆する銀被膜2と、を備える。そして、銀被膜2は銀被覆材料の最表面に配されている。また、銀被膜2の表面2aには粒状の突起2bが複数形成されていて、銀被膜2の表面2aの局部山頂の平均間隔Sが0.3μm以上3.0μm以下であり且つ十点平均粗さRzが0.3μm以上10.0μm以下である。【選択図】図1 |
