Abstract

With the laser cladding technology, 70%Ni60A+30%WC cladding layer was cladded on the surface of Q345 steel. And the phase, microstructure and wear resistance of cladding layer were analyzed. Experiments show that the Ni-based WC alloy laser cladding treatment on Q345 steel surface have a great upgrade on grain refinement, surface hardness and wear-resistance of Q345 steel surface.
