Coated Diamond Powder
Coated diamond is divided into electrolytic and chemical plating, it includes Ni coating, Cu coating, Ti coating, Cr coating etc. Coated diamond effectively increase holding force between diamond and bonding, reduce thermal shock, protect diamond against oxidation and graphite, lengthen product lifetime.
HID Ni Coated Diamond
Description:Nickel coating diamond powders are generally divided into two different produce coating types: electroplating and chemical plating;
Two different gain weight way: gain weight 30%; gain weight 56%.
Rough and spiny surface, improve the retention between diamond and bond, avoid the diamond peeling off early, thus, extend the service life of diamond tools.
Recommend for making resin bond diamond tools.
Application: Electroplating Nickel products mainly used in resin bond products with dry and wet abrasives, effectively improve the holding force with good thermal stable ability, avoid carbonization in high speed cutting. Chemistry plating Nickel products mainly used in resin bond products with dry and wet abrasives, no external current conditions, and deposited metal on diamond surface by process of self-catalytic redox reactions, form the thickness and density of nickel-plated.
Grade HID Cu Coated Diamond
Description: Recommend for resin bond tools. Able to effectively enhance the tools life by improving the mechanical retention of diamonds and reducing heat damage.
Characteristics: Effectively enhance the tools life by improving the mechanical retention of diamonds and reducing heat damage.
Grade HID Ti Coated Diamond
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.
Grade HID Si Coated Diamond
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.
Grade HID W Coated Diamond
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.
Grade HID Co Coated Diamond
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.
Grade HID Cr 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.
