主　　题：supersonic atmospheric plasma spraying(SAPS) TiB2−SiC coating vacuum calcination processing optimization 

摘      要：With the TiB2−SiC powders after spray granulation and vacuum calcination as raw materials,the TiB2−SiC coating was prepared by supersonic atmospheric plasma spraying(SAPS).The effects of spraying power and spraying distance on the properties of the TiB2−SiC coating were investigated and the fabrication processing of SAPS was *** results show that the sprayed powders after calcination have a uniform particle size distribution,good sphericity and enhanced *** coating prepared by the calcined powders has a dense structure and high deposition *** the calcined TiB2−SiC powders are used and the spraying power is 95 kW and the spraying distance is 150 mm during supersonic plasma spraying,the obtained TiB2−SiC coating behaves the best comprehensive performance with the porosity,microhardness,bonding strength and resistivity equal to 5.6%,3.57 GPa,18.3 MPa and 10.8 mΩ·cm,respectively.
