Silicon Carbide #4000 powder for Boron Nitride Coating
During the aluminum casting process, components such as runners, molds, and slag rings, which frequently come into contact with high-temperature molten aluminum, can be sprayed with boron nitride coatings to effectively enhance their high-temperature and corrosion resistance, thereby extending their service life. Adding Silicon Carbide #4000 powder (3-5µm silicon carbide powder) to boron nitride coatings can improve the coating’s performance in several ways.
