The most common existing form of chromium in Guangdong mechanical processing plant is used in stainless steel as an alloying element to enhance the hardness of stainless steel. Chromium plating process is usually divided into three types: decorative coating, hard chromium coating and black chromium coating. Chromium plating is widely used in engineering field. Decorative chromium plating is usually used as the top layer of nickel coating, and the coating has the polishing effect of exquisite and delicate as mirror. As a decorative post-treatment process, the thickness of chromium coating is only 0.006 mm. When Guangdong Machinery Factory plans to adopt chromium plating process, it must fully consider the risk of this process.
In recent ten years, the trend of hexavalent decorative chromium water being replaced by trivalent chromium water is more and more obvious, because the former has very strong carcinogenicity, while the latter is considered to be relatively less toxic. Material characteristics: very high finish, excellent corrosion resistance, hard and durable, easy to clean, low friction coefficient. Typical uses: decorative chromium plating is the coating material of many automotive components, including door handles and buffers. In addition, chromium is also used in bicycle parts, bathroom faucets, furniture, kitchen utensils, tableware, etc. Hard chromium plating is widely used in industry, including ram in job control block, jet engine components, plastic mold and shock absorber. Black chrome plating is mainly used for musical instrument decoration and solar energy utilization
