Iridium-plated white corundum is a special abrasive made by using high-quality corundum as raw material, undergoing high temperature and heat treatment, and coating a layer of metal iridium composite material on the surface of the abrasive. After calcination, it is made. After iridium plating, corundum has significantly improved toughness, rougher surface, stronger hydrophilicity, increased self-sharpness, and improved heat dissipation performance. In the process of making grinding wheel products, it can be better combined with adhesives. The produced grinding tool products have characteristics such as high work efficiency, and long service life, and are not easy to burn workpieces. Iridium-plated abrasives improve white corundum abrasives by adopting new materials and technologies based on traditional abrasives. Compared with ordinary abrasives, it increases microhardness by 10%, toughness by 10%, hydrophilicity by 35%, grinding efficiency by 30%, and durability by 30-50%, which is very helpful for improving the quality of grinding wheel products. In addition, iridium-plated white corundum can be used in precision casting molding sand, spraying materials, special ceramic product raw materials, advanced refractory materials, and other fields.
