Patents Assigned to Tsuneki Metal Plating Industries Co., Ltd.
  • Patent number: 6878461
    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 structure 1 having a plating layer formed on the surface of a substrate 2 comprises a lubrication plating layer 5 made of a plating layer of a metal matrix containing fine particles 4 having lubricating property, and a noble metal plating layer 7 formed on the lubrication plating layer 5. Preferably, an anti-diffusive plating layer 3 made of a metal plating layer is formed under the lubrication plating layer 5, and a joining layer 6 made of a strike plating layer of noble metal is formed between the lubrication plating layer 5 and the noble metal plating layer 7.
