| Summary: | Title screen Cubic tungsten carbide WC1-x is one of the most poorly studied phases of the W-C system due to the difficulty of obtaining WC1-x by most known methods and its instability under heating. This makes it difficult to obtain WC1-x in bulk form and measure its physical and mechanical properties. In this work, cubic tungsten carbide was synthesized in the form of a coating by the plasma dynamic method. The process was implemented under highspeed spraying of an electric discharge W-C plasma on copper and titanium substrates. As a result, the coating has a sandwich structure Cu-WC1-x -Cu substrate) or (TiC+WC1-x )-Ti-(WC1-x+TiC)-Ti(substrate) with a thickness of the WC1-x layer up to ~10 [mu]m, Direct measurements of WC1-x mechanical properties were carried out for the first time. The maximum values of nanohardness and Young's modulus of the WC1-x layer areHv=31.0±0.8 and E=310±12 GPa respectively. Режим доступа: по договору с организацией-держателем ресурса |
