The coating greatly enhances the mechanical attachment of diamond to the bond matrix through the strong metallurgical adhesion between Ti and the matrix. It also protects diamond from oxidation or metal erosion which causes graphitization of the diamond, therefore, improves the application features of diamond tools.

Thanks to our R&D team, ZZDM develops one special electroless Nickel coating, which greatly enhances the retention between diamond particles and the bond, thus to prolong the tool's life and improve the sharpness. This special Nickel coating products offer a better performance compared with the typical products in the market.

Recommend for resin bond tools. Able to effectively enhance the tools life by improving the mechanical retention of diamonds and reducing heat damage.

Silicon coating strengthens the retention between bond and diamond, improves the thermal stability, wear resistance and helps better conduct the heat. It also helps to avoid the corrosion from Fe, thus it protects the diamond, prolongs the tools' life and raises the sintering temperature.

W reacts with diamond particles and generates WC, which is with good thermal stability and wear resistance. The coating improves the bond retention and enhances the diamond toughness, its alloy coating layer improves the thermal conductivity, which can prolong tool life.

Cobalt coating could improve the retention of diamond and bond. In addition, the sintering temperature could be raised because the coating can protect diamond from oxidation and corrosion. It also enhences the hardness and abrasive resistence of coated diamond.

Chromium enjoys nice wettability and affinity on diamond. It forms a layer of chromium-carbide between diamond and bond during coating and sintering, thus the coating improves the retention between diamond and bond. It also increases the hardness and abrasive resistance of coated diamond.

Nickel alloy coated product. Gully structured surface improves the retention between the coating layer and the bond. The TNC coating also decreases the diamond concentration, extends the tool’s life span and reduces the power consumption.

Spiky nickel alloy coated product. The coating protects the diamond from being eroded, enhances the bond retention. The spiky surface also increases the working height of diamond particle, so as to improve the cutting efficiency, prolong the tool’s life and improve the sharpness.

Corundum coating is very spiky and rough in the diamond particle surface, which improves the bond retention and prevents diamond particles getting off from the bond. The coating also improves the working efficiency and prolongs tool life dramatically.
