METHOD FOR FORMING HARDWEAR-RESISTANT COATINGS AND THE COATEDARTICLE PRODUCED THEREBYABSTRACT OF THE DISCLOSUREA hard wear-resistant coating for a metallic substratewhich is achieved by preheating the substrate to a temperaturein the range of from 350°C. to 1000°C. and depositing thecoating material with the plasma or detonation-gun (D-gun)process while maintaining the substrate within the 350° to1000° temperature range to form a fine dispersion of carbideparticles in the coating.S P E C I F I C A T I O N-1-
