ABSTRACT:
There is provided contact, sliding, fitting-in and ornamental members having a surface treatment structure in which contact resistance is low, and lubricating property and wear resistance are excellent, and capable of being used suitably for any use of contact, sliding, fitting-in or ornament, and a method for manufacturing the same. The surface treatment structure1having a plating layer formed on the surface of a substrate2comprises a lubrication plating layer5made of a plating layer of a metal matrix containing fine particles4having lubricating property, and a noble metal plating layer7formed on the lubrication plating layer5. Preferably, an anti-diffusive plating layer3made of a metal plating layer is formed under the lubrication plating layer5, and a joining layer6made of a strike plating layer of noble metal is formed between the lubrication plating layer5and the noble metal plating layer7.
