摘      要：A certain amount of Ti was added to the plasma cladding Fe-Cr-C coating in the early stage in order to improve the quality and properties of the ***-Fe-Cr-C composite powder was prepared by precursor carbonization-composition *** situ synthesized TiC-Fe-Cr coatings were fabricated on substrate of Q235 steel by plasma cladding process with the composite *** of the coatings with different process parameters,including cladding current,cladding speed,number of overlapping cladding layers,were analyzed by scanning electron *** results show that the structure of the TiC-Fe-Cr coating is greatly affected by the cladding current,the cladding speed and the overlapping cladding *** this test,when the cladding current of 300 A and the cladding process parameter of the cladding speed of 50 mm/min are clad with three layers,a well-formed and well-structured TiC-Fe-Cr coating can be obtained in this ***-Fe-Cr coating has good wear resistance and good load characteristics under dry sliding wear test conditions.
