| Abstract: | On the surface of Q235 steel,the cladding layers have been produced by laser cladding.The variation of the microstructures,the distribution of surface microhardness and its cause,the enhancement of the surface wear resistance were discussed.The results showed that: the hardness and wear resistance of the laser cladding layer can be improved to some extend because of the additional tungsten carbide. |
