поликристаллического алмаза порошок производится детонации

polycrystalline diamond (PCD) is similar with natural Carbonado in the structure. There’re thousands of micro crystallites size of 3-10nm integrated together into polycrystalline structure through unsaturated bond. PCD has many more cutting surfaces, resulting in the higher removal rates. It also has good self-sharpening properties. The polycrystalline structure will open every time new sharp edges introduced by releasing an outer layer of dull crystallites. The polycrystalline diamond can lap and polish any materials fast while produce the smoothest surface without scratches. Application: Used as high precise abrasives: Sapphire process, such as back lapping and polishing of sapphire-based LED epitaxial wafers Lapping andpolishingof magnetic heads, hard disk, CMOS chips, ceramics, glass, hard alloy, optics lens, etc Used as additives for the electroplating films of metal molds, tools, metal parts to improve their wear resistance, surface hardness and service life available sizes: 0-0.05, 0-0.1, 0-0.125, 0-0.2, 0-0.25, 0-0.5, 0-1, 0-2, 1-2, 1-3, 2-4 , 5-7, 5-10, 6-12, 8-12, 8-16
