Abstract:Three Ni-based alloys (Ni60, Ni65, Ni60W) were selected to be coated on the surface of 40Cr and 20 steel. The microstructure, phase composition and elemental distribution of the coatings were characterised respectively to discuss the effects of different substrates, cladding materials, and preparing processes. The corrosion and thermal fatigue behaviour of the coatings were investigated. The results show that the coatings prepared by plasma cladding have a dense microstructure with few defects and a white brig… Show more
