[Abstract]:
The main purpose is to improve the composite plated coating of corrosion resistance, abrasion resistance

The main purpose is to improve the composite plated coating of corrosion resistance, abrasion resistance, lubricity, improved surface appearance and improve other features. Iron substrate, the protective decorative coatings commonly used Cu-Ni-Cr and Ni-Cr multilayer coating composition. And like a car like baffle exposed decorative parts, to improve the corrosion resistance, the surface layer of microporous chrome plating must, in order to increase the exposure of key areas, dispersing corrosion current. Obtain a microporous chrome plating in two ways, graphite is added to obtain a microporous chrome plating solution in chrome, bright nickel plated or plated with a layer of Ni-SiO2 composite coatings (commonly known as Nickel closed), and then chrome-plated to give a slightly hole chrome plating. After the actual production of a method used up, the number of microporous chromium plating layer obtained per square millimeter 400 to 800 as well.
