Plated material and plating pretreatment method

Abstract

A plated material containing a base material and a metal plating that covers the base material, the base material containing a main raw material free of any carbon materials, and a carbon material that is present inside the main raw material. A plating pretreatment method including a first step of preparing a base material from a main raw material free of any carbon materials and a carbon material, the base material containing the main raw material and the carbon material that is present inside the main raw material; and a second step of charging the base material into a treatment tank, and immersing the base material in a supercritical fluid or subcritical fluid containing an organometallic complex of palladium in the treatment tank.

What is claimed is: 
     
         1 . A plated material comprising:
 a base material; and   a metal plating that covers the base material, wherein   the base material contains a main raw material free of any carbon materials, and a carbon material that is present inside the main raw material.   
     
     
         2 . The plated material according to  claim 1 , wherein the carbon material is contained in an amount of 0.1 mass % or more and 3.0 mass % or less with respect to the base material. 
     
     
         3 . A plating pretreatment method comprising:
 a first step of preparing a base material from a main raw material free of any carbon materials and a carbon material, the base material containing the main raw material and the carbon material that is present inside the main raw material; and   a second step of charging the base material into a treatment tank, and immersing the base material in a supercritical fluid or subcritical fluid containing an organometallic complex of palladium in the treatment tank.
