Coated Diamond Powder

The normal diamond cystals may pull out from diamond tools during use, coated diamond powder is created to improve the pulling out situation. The coatings on the surface can increase the particle retention. And it could help to do better heat dissipation in most bond systems and increases the life of tools.

• Surface roughness of the diamond powder will be improved after coating, and bonding strength will be improved accordingly.
• The coating layer protects the diamond powder by reducing thermal impact during sintering, cutting, grinding & polishing and protect the diamond powder from oxidizing or graphitizing
• Heating dissipation capability will be dramatically improved after being coated, diamond grit can withstand the strong cutting/grinding force and temperature service life of the diamond powder will be increased.
• Wettability of the diamond particles are improved after coating which allows for better dispersion and distribution of the diamond in the matrix material, ensuring a more uniform and efficienct abrasive action.
• Coatings can also provide chemical stability to the diamond particles,  protecting them from the chemical reactions with the workpiece material or environment. This is particularly important in applications where the diamond may come into contact with coroosive substances.

We do electroplating coated and chemical coated diamond powder, and predominately Nickel coated (Ni-coated) and Titanium ( Ti-coated) coated. Nickel coated diamond grit is recommended for resin bond diamond tools. Diamond retention is improved. Life span of the resin bond tools and workpiece surface finishing will be enhanced accordingly. Titanium coated diamond  is recommended for metal bond diamond tools. It will significantly improve tool's life and efficiency.
