1、Chrome plating chromium plating for steel parts for Yin polarity coating.
2、Special treatment is recommended to activate beryllium copper surface before chromium plating. And special steps which differ from conventional chromium plating on steel parts are to be taken.
3、Cylindrical anodes are conventionally used for chromium plating on surface of cylindrical articles.
4、Formate-A acid system was a sulfate trivalent chromium plating process with low concentration.
5、Hexavalent chromium plating has weaknesses such as toxicity and environmental pollution.
6、For example steel base plated copper, nickel, chromium plating, low layer again tin bronze chrome, multi-layer nickel chrome plating nickel ferroalloy, chrome, and so on.
7、Add in the milky white chromium plating chromium, called light wear double chrome plated. In the plane, shipping parts and guns lumen is widely applied.
8、Orthogonal test of decorative and protective chromium plating process Part III-Evaluation methods and standards for deposits
9、A process of alkaline hard chromium plating on aluminum alloy was presented, including oil removal, dipping in heavy metal solution, acid pickling, dipping in zinc solution, hard chromium plating.
10、The basic principle and the improvement of Santana spherical cast iron piston ring chromium plating technology is briefly introduced.
11、The deduction is confirmed by establishing self locking conditions and determining the sliding friction coefficients between sand and chromium plating layer and between sand and nitrided surface.
