  • Chrome-plated part and manufacturing method of the same
    Patent number: 9650722
    Abstract: An nickel plating layer (5a) intended for corrosion current distribution is formed over a body (2), and a 0.05 to 2.5 micrometers thick surface chrome plating layer (6) made of trivalent chromium is formed on the surface thereof using basic chromium sulfate as a source of metal. Further on the same, a not less than 7 nm thick chromium compound film (7) is formed by cathode acidic electrolytic chromatin. The corrosion distribution nickel plating layer (5a) has a function of forming a microporous structure, a microcrack structure, or the both of the same in the surface chrome plating layer (6).
    Type: Grant
