In this paper, WC-Ni60 alloy composite coating with different contents of WC particles was prepared on the 45steel substrate by high frequency induction cladding. The Composition and microstructure were characterized by X-ray diffraction (XRD) and electron probe X-ray microanalysis (EPMA), the abradability and hardness were tested by UMT-2 tribometer and HV-50A durometer, respectively. The results showed that the hardness and wear resistance of coating were enhanced with the increasing of WC content. WC-Ni60 coating obtained the best wear resistance with the content of 50% WC. The hardness of the coating got the highest when the content of WC was 60%, but wear resistance decreased. The WC-Ni60 coating was reinforced for various hard phases and the metallurgical bonding layer about 10μm was formed between coating and 45steel substrate.
