Failure of mechanical parts usually occur on the surface or start from the surface, such as wear, oxidation corrosion and fatigue. This work uses high frequency induction cladding technology to improve the overall performance of stainless steel surface. A layer of WC and stainless steel is coated on the surface of the stainless steel. The effects of different WC material contents and different induction heating current intensities on the cladding were analyzed. After the preparation of the sample, the morphology and properties of the cladding layer were analyzed by SEM, XRD and other test methods. The results show that when the content of WC is 2%-3%, the heating time is 90s and the heating current is 860A-890A. The surface of the cladding layer is most densely formed and there is no obvious over-burning phenomenon and pore generation.
