Аннотация
A mechanism of nucleation and formation of Ti–Cr coatings on synthetic diamond powders of grade HSD 90 has been revealed and investigated. The metal deposition has been found to occur selectively and heal surface defects (microcracks, steps, etc.). Ti is the matrix metal that forms the coating as a whole, while Cr is the alloying element. Thermal stability of metal-coated diamond powders has been studied by derivatography. It has been found out that in comparison to non-coated powders the coated ones have the oxidation resistance increased by 40°C and feature an interdiffusion at the coating–bond interface.
