Preparation and properties of ultra-high temperature ceramics based on ZrC and HfC

Original language description

Successful preparation of massive compact bodies from ultra-high temperature ceramics like zirconium carbide, hafnium carbide and their cermets with tungsten matrix with high values of mechanical parameters is difficult. Only limited number of techniquesis able to perform it because of their absolutely highest melting points. In our contribution the preparation of these materials by hot-pressing and plasma-spraying is described and chemical processes taking part at the processing are studied. Hot-pressed products fabricated at 2000°C and 6 GPa react with the internal surface of the BELT-type apparatus. Melting and sintering is taking place at plasma spraying. This process carried out by water stabilized plasma torch with centerline temperature up to 30000 K, is joined with undesirable reactions with plasma-forming medium, with oxidation in a turbulent plasma flow and nitridation of free-flight particles. All these chemical processes depend on variety of parameters, such as particle si
