Chrome Plating -- Influence of Material Composition on Appearance


I am doing research work at UW-Milwaukee in metal surface finishing and machining. My question is in regard to electroplating (Chrome plating) leaded brass. If the chemical composition of brass changes in regard to content of Copper,lead,Zinc,Iron and silicon will the appearance of the surface after chrome plating (specifically the shine) have an impact. Surface finish of the brass body after polishing is ~12 to 16 microinch.

When properly polished and nickel plated, then chrome plated, you will have no clue of the substrate composition from the appearance. You will probably, however, have a very good indication of the surface finish prior to plating.

Want to know how much a chrome plating machine will cost.

Somewhere between $500 and $5 million, although sometimes a little higher. Probably the biggest question is what you intend to do with it, because plating is one of the most highly regulated businesses in America.
