Abstract : Since a commercially available plasma powderspraying head (Giannini Model no. SG-1) gave a satisfactory Al2O3 distribution in the plasma stream, it is planned to use this equipment for erosion experiments on W. An inert atmosphere chamber was built to prevent W oxidation. Details of the thermal shock apparatus are presented. Radial and circumferential thermal shock cracks were obtained on 90 and 87% dense sintered W ring specimens, respectively.
