Abstract:
     A process for preparing the high-smelting-point ceramic layer or ceramic-metal layer on the surface of substrate includes such steps as conventional pre-treating on the surface of substrate, charging the powder material to be sprayed in the cavity of spray gun, applying a high shock current to electrodes, electric explosion for preheating and pushing said ceramic powder to the inlet of stage-2 spray gun, breaking through its electrode for generating high current and forming a plasma channel, heating and pushing the powder to move forward at high speed, and colliding with the surface of said substrate to form said ceramic layer.
