230/270 Artificial Cubic Boron Nitride CBN Superabrasives​

 

Description:

Diamond has the advantages of high thermal conductivity, low density, high hardness, high compressive strength and thermal expansion coefficient and good matching with semiconductor materials. However, because diamond sawing tools and drilling tools are mostly produced by powder metallurgy, sintered The temperature can generally be as high as 900°C. However, when diamond is heated to about 700°C in the air, the problems of weight loss and compression resistance begin to occur; when the temperature is above 1000°C, the diamond will undergo graphitization, and the surface energy of the diamond is very high. High, and the wettability of diamond with the matrix is ​​relatively poor, and the adhesion with the matrix is ​​weak. Generally, the connection between diamond and the metal matrix only depends on mechanical inlay force, but it cannot form strong chemical bond adhesion, which makes the diamond easy to work. Fall off. In order to achieve the purpose of enhancing the wettability between diamond and metal, the method of electroless nickel plating on the diamond surface with sodium hypophosphite as a reducing agent is generally used to reduce the interface energy between the diamond and the matrix and improve the wetting between them. Wetness. At the same time, the different weight gain rates before and after the diamond surface plating also have a certain impact on the diamond performance.

 

Ni Coating Diamond Powder
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.

 

Ti Coating Diamond Powder
Through forming a dense layer of Titanium coating, it can avert to oxidize and graphitize when the diamond powder during the high-temperature diamond tools manufacture circumstance. Thus reduce the heat damage and keep the good hardness, and thermal stability features, then effectively extend the service life of diamond tools.
Recommend for making metal bond and vitrified bond diamond tools

- Grade HID Si Coated Diamond
Silicon coating diamond powder 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 diamond powder 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 coating diamond powder 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.
