Iridium-coated brown corundum is a brown corundum abrasive product with a special surface treatment. Its performance is enhanced by coating a layer of metal iridium oxide (or iron oxide, there may be terminology confusion in some materials) on the surface of brown corundum. The following is detailed information about this product:
1. Product definition and process
Iridium-coated brown corundum is a new type of abrasive made of ordinary brown corundum or calcined brown corundum. After high-temperature heat treatment, a layer of metal oxide (such as iridium oxide or iron oxide) is coated on the surface of the abrasive through a specific process12. This process combines traditional abrasive technology with modern material science to improve the physical and chemical properties of the abrasive.
2. Main performance characteristics
Improved hardness and toughness: Compared with ordinary brown corundum, the microhardness is increased by about 10% and the toughness is increased by 10%1.
Enhanced hydrophilicity: The hydrophilicity is increased by 3.5 times, making it more suitable for applications that require good wettability such as coated abrasives and resin grinding wheels1.
Improved grinding efficiency: The durability is increased by 30-50%, and the grinding efficiency is increased by 30%1.
Surface property optimization: purer particles and rougher surface improve the bonding strength with the binder1.
3. Main application areas
High-end abrasive tool manufacturing: such as resin grinding wheels and coated abrasive tools, suitable for precision processing of high-hardness alloys, hardened steel and other materials12.
Refractory materials and ceramics: used to improve the hardness and wear resistance of ceramics7.
Electronics industry: can be used for cutting and polishing tools for semiconductor wafers6.
4. Market and production situation
Main manufacturers: Luoyang Weixiang Abrasives and Tools, Yuzhou Yinxing Abrasives and other companies provide such products, and some companies have an annual production capacity of thousands of tons134.
International demand: China is the world’s major producer of brown corundum, and high value-added products such as iridium-plated brown corundum are gradually expanding international markets, such as Europe, Southeast Asia and other places
