Abstract: [eng] [cze]
Cermets of the HfC in W matrix were prepared firstly by hot pressing at the temperature 2000°C and pressure 5.5 GPa and secondly by plasma spraying using water stabilized plasma gun WSP. Microhardness, elastic modulus and thermal expansion coefficients were measured for 10 % HfC and compared with pure tungsten. Cermety karbidu hafnia ve wolframové matrici byly připraveny jednak metodou hot pressing při teplotě 2000°C a tlaku 5,5 GPa a dále metodou plasma spraying pomocí generátoru vodou stabilizovaného plazmatu WSP. Byly změřeny a porovnány hodnoty mikrotvrdosti, modulu pružnosti a koeficienty teplotní roztažnosti vzorků s obsahem 10 % HfC.
