| Popis: | Structure formation in laminated coatings (Si + C) and a cobalt alloy ЭП 131 on magnetronically sprayed diamond crystals with subsequent heating in a dilatometer up to 1400 °C is accompanied by formation of amorphous and crystal SiC-layer within temperature interval of 650–850 °С and a layer of cobalt ЭП-alloy. Adding of KCR06-hard alloy granules in furnace charge leads to sintering of tungsten carbide inside of the granules and with diamond crystals through SiC coating and alloyed cobalt binder at temperature of 1400 °C. |
