Abstract:
     The present invention is composite coating of ceramic-metal compound and its preparation process. The preparation process includes the following five steps: preparing heat reaction powder, preparing, preparing, turning off all switches and arranging the processed workpieces. The heat reaction powder is one Fe-Al-TiO2-B2O3 system comprising Fe powder, Al powder and TiO2 powder of 150-200 mesh fineness as well as B2O3 powder of 100-150 mesh fineness. Under the action of plasma heat excitation and the auxiliary action, the powder system takes chemical reaction in plasma flow to form metal phase and intermetallic compound phase on the surface of the workpiece to combine metallurgically with the substrate surface in micro melting state. The coating may have regulated hardness and controlled thickness, and the process has less deformation of workpiece and high efficiency.
