Study of Plasma Cladding Ni-Based Compound Powder Layers on Q235 Steel

Abstract:

By plasma cladding technology, the Ni60B/TiC composite coating metallurgically bonded to Q235 steel were prepared using Ni-based alloy and TiC powders. The microstructure formation mechanism of the clad layers was investigated by scanning electron microscopy (SEM) and X-ray Diffraction (XRD). The microhardness distribution and wear resistance of the specimens were tested. The results show that metallurgical combination is achieved between coating and substrate, the microstructure of composite coating is composed of dendrite γ-Ni, α-Fe, added TiC and FeNi. The hardness and wear resistance of composite coating have relationship with TiC particles content and TiC particles distribution. The hardness and wear resistance increase with the increase of TiC particles content.
