Diamond plated metal at a certain temperature to prevent

Diamond plated metal at a certain temperature to prevent, under the conditions of pressure and sintering time of oxidized graphite and hot corrosion resistance of iron. The author of the different metals plated diamond for TG (TG) analysis, discovery of diamonds began at  PSA sanding disc about 800 ℃ weightlessness and graphite. The coated Ti, W, TiN, etc., respectively diamond 900 ℃, 925 ℃ and 940 ℃ weight loss when starting and graphitized. Description diamond plated metal back helps prevent oxidation and graphite, can withstand thermal shock and thermal decomposition. High temperature sintering carcass showed a protective effectStrong carbide plating element in the sintering conditions can be formed at the interface of diamond and  ceramic belt the matrix alloy carbide, diamond and matrix conducive to chemical bonding with the metal metallurgical bonding, greatly improving the gripping force of the matrix of the diamond, the diamond coated tungsten X-ray analysis showed that the surface of the diamond has been formed with WC. 
he static strength of the diamond can be increased from 5% to 20%. Diamond plated metal, may increase cut off disc  the friction of the diamond, which helps increase the holding force. 3. Fine powder and pre-alloyed powderIn the production of special saw blade, should adopt the ultrafine metal powder and pre-alloyed powder. Metal powder sintering temperature helps reduce thinning, increased hardness. Use of pre-alloyed powder, low melting point metal to prevent premature loss and segregation, sintered products in favor elastic limit and yield strength, to increase the gripping force of the diamond, but also reduce the sintering temperature and holding time.
