| Abstract: | Ni-based composite coating reinforced by TiCp particle was prepared on the surface of 45 steel by means of argon arc cladding technique with the pre-alloyed powder of Ni60A,Ti and C.The microstructure and properties of the coating were investigated by scanning electron microscope,X-ray diffractometer and microhardness tester.The results show that the interface of coating and 45 steel substrate is metallurgical bonding and the coating is uniform,continuous and almost without defect.Microstructure of the clad... |
