02 Secondly, add carbon powder element to improve the diamond holding power. In the process of diamond saw blade processing, if the cutter head matrix has a good grip on the diamond, the diamond will have a good edge, will not fall off prematurely, and the cutting will be sharp and efficient. Generally, metal elements, such as plating, titanium, chromium, nickel, tungsten, etc., can be formed by coating the surface of diamond with a layer of strong carbon compound, so as to improve the bonding between diamond and matrix powder, and help prevent diamond from sintering at high temperature. In addition, a small amount of strong carbon powder elements can be added to the matrix powder, such as molybdenum, chromium, tungsten powder, etc. Since this type of powder has good wettability and affinity for diamond and diamond, carbide alloys are formed on the surface of diamond and matrix metal during sintering, which is conducive to the chemical bonding and metallurgical bonding of diamond and matrix metal, thereby greatly improving tire placement. The body's holding power to the diamond.
