| Abstract: | By plasma cladding technology,high hardness coating with Fe-based alloy+TiC powder was prepared on Q235 steel.The microstructure of the coatings was investigated by optical microscope (OM) and X-ray diffraction (XRD),and the microhardness was also tested.The results show that the composite coating mainly consists of low-carbon martensite,and TiC particle mainly distributes in the grains and grain boundaries.The micmhardness of the coatings increases with the increase of TiC content. |
