| Abstract: | The influences of laser power,scanning speed and off-focus on the properties of layer cladding Ni/WC-Y2O3 on the surface of 35CrMo steel were studied.Choose the right levels to make the orthogonal experiment,then the laser cladding process parameters which adapt to produce the excellent hardness and surface wear properties of the cladding layer could be got.In addition,the influence of WC and Y2O3 to the microstructure properties of the cladding layer was also analyzed. |
