Abstract
The present invention provides a nickel and/or chromium plated member comprising a substrate, a pretreatment plating layer deposited over the whole substrate on which a copper plating layer is formed, a functional layer formed on the copper plating layer in which the functional layer has a low potential nickel layer and a microporous nickel layer formed on the low potential nickel layer, and a decorative layer formed on the microporous nickel layer. In this invention, the microporous nickel layer and the low potential nickel layer provided on the surface of the member significantly improve the corrosion resistance and stability of the whole member and provide good brightness uniformity and binding effect of the plating layers.
