簡介
Chromium
(Symbol Cr) silver-white, very hard and brittle metal. Chromium ischemically stable and is hardly oxidized under moist air. Innon-oxidizing acids such as HCl it dissolves under generation of hydrogenand chromium salts, oxidizing acids hardly corrode chromium, even uponheating, due to passivation. Chromium coatings for corrosion protectionand for decorative purposes are produced by electroplating and, in fewcases, by CVD. Chromium steels feature high corrosion and heat stability.Cutting metals are alloys from Co, Cr, and W.
