Chromium nitride (CrN) is a chemical compound produced by reacting chromium with nitrogen. It is used as a wear-resistant, corrosion-resistant, and heat-resistant coating in various industries. This coating is applied to metal surfaces, particularly in the automotive industry and tool manufacturing, to enhance durability and performance. Chromium(III) nitride can be prepared by direct combination of chromium and nitrogen at 800 °C.
