The laser cladding technique in 35CrMo steel substrate prepared with different dosage under WC iron-based alloy
cladding.Research the effects of different cladding WC addition on surface morphology, microstructure, microhardness
and wear properties. The results show that 5% and 10% WC added amount of the surface quality of the cladding layer is
preferably 15 % and 25 % of the volume of the WC surface of the cladding layer with varying degrees of cracks and
pores, WC adding cladding layer can significantly improve the hardness. Through analysis we draw the conculation
that,with 10% WC addition of iron-based alloy cladding the microhardness is 4.2 times the substrate , the relative wear
resistance increased 4.1 than the substrate , enabling optimum cladding friction and wear properties.
