As for the three basic differences of electroplating
1: "chromium plating is mainly to improve the surface hardness, beautiful, rust. Chromium coating has good chemical stability, in alkali, sulfide, nitric acid and most of the organic acid are not in action, but can dissolve in hydrohalide acid (such as hydrochloric acid) and hot sulfuric acid. Because chromium does not change color, when used can keep its reflectivity for a long time and is better than silver and nickel. The process is generally electroplating.
2: nickel plating is mainly wear-resisting, anti-corrosion, anti-rust, general thickness is relatively thin, the process of electroplating and chemical classification.
3: galvanized is mainly beautiful rust protection. Zinc is a reactive metal that reacts with acids, so it has poor corrosion resistance and is the cheapest of the three.
The difference of cost respect plating chromium is most expensive, nickel is next, zinc is cheapest, among them still want to distinguish hang plating, roll plating to wait. Hang plating is expensive, roll plating is cheap
Chrome plating bright white, nickel plating a little yellow, galvanized silver white (in fact, there are color zinc, gray zinc, matte chromium, bright chromium, white nickel, black nickel, etc.
