| Abstract: | It was obtained that the reasonable process of laser cladding was consonant with making swear-resistant layers on 45 steel baseplate by using the high Cr and iron-based alloy powder.It was analyzed that the performance of cladding layer included microstructure,microhardness and tempering character and that the wear resistant was contrastively tested by the wear test and by the scanning electron microscopy between tempering and no.It is showed that the microstructure is homogeneous and smaller and that the w... |
