In order to increase the adhesion of artificial corundum to other raw materials, it is necessary to attach a layer of iridium plating to the outer surface of artificial corundum to increase the adhesion to the raw materials during high-temperature extrusion. The current plating raw material of iridium is mostly water glass. This raw material has insufficient holding power. The friction and collision of artificial corundum can easily cause falling off, which affects the quality of artificial corundum.

In the abrasives tool industry, it needs an abrasive grain of high roughness, we develop iridium-coated white corundum, mix the surface of each grit with iridium coating, and bake it at high temperature.

Advantages of Iridium plated white corundum has apparent advantages as below:

1.High roughness

2.High bonding ability because of improved water affinity, improved self-polishing ability.
Therefore, when creating bone-in abrasives and abrasive cloth tools, the grit is more easily glued with a bonder of resin, glue, ceramic, etc.
3. Improve the performance of abrasives tools such as cutting wheels, grindstones, and flap discs made of iridium-coated aluminum oxide to provide sharper, longer life and higher work efficiency.
