Applications
Pure chrome powder is for electroplating, which is one of the most important electro-deposited metal. In most situation, chrome coating specially works as the outermost coating. When depositing chrome powder, thiner chrome coating, closer to the metal’s surface. Coating of Inwall of some gun barrel is just with thickness 5microns, however after launching hundreds of cannonball or bullets, the chromium coating still exist. With the property of chrome coating, most parts’s lifetime would decrease due to abrasion and corrosion. Chrome metal powder also take a part in production of brake block in automobile industry.
