Description of the development:
()
Currently widely used composite materials based on polycrystalline diamond and silicon carbide formed during silicon impregnation with diamond powder under high pressures and temperatures. The microstructure of these composites is typically a frame made of diamond particles (80-90% of total volume) between which are silicon carbide and uncombined crystalline silicon. The main disadvantages of these materials - increased fragility and low percentage of product yield. The ISM has developed a new material characterized by high strength, high yield rate of products from this material. It is found that this can be achieved by introducing into the impregnating nanopowder layer of diamond or silicon carbide. The addition of diamond nanopowder impregnating Si-layer in the preparation of the composite contributes to the formation of a uniform finely binder phase SiC at the almost complete absence in it of unbound silicon. These factors determine the increase in strength of the composite, and the yield of products. Available in two grades of material: increased strength and increased abrasion resistance.
