| Abstract: | Wear is one of the main factors affecting the service life of dumper cars.In this study,laser cladding method was used to prepare the cladding layer containing TiC and VC reinforced particles.The microstructure of the reinforced particles was analyzed by X-ray diffractometer,EPMA and TEM.The wear resistance of the cladding layer was studied by sliding wear tester.The results show that the wear resistance of laser cladding layer is better than that of Q235 plate. |
