CHROMIUM-PLATED PART AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a chromium-plated part which has corrosion resistance in ordinary and specific environments and eliminates the need of additional treatments after chromium plating and its production method.SOLUTION: A chromium-plated part 1 includes a basis material, a glossy nickel plating layer 5b formed on the basis material 2, a noble potential nickel plating layer 5a which is formed on and adjacent to the glossy nickel plating layer 5b and has a potential difference between the glossy nickel plating layer 5b and it of 60-120 mV and a trivalent chromium plating layer 6 which is formed on and adjacent to the noble potential nickel plating layer 5a and has at least one of a microporous structure and a micro-crack structure.
