The work aims to prepare Ni-based coatings enhanced by TiB2 on 35CrMo steel by using frequency induction cladding technology, and study the law of influence of TiB2 content on microstructure, hardness and abrasion resistance of Ni-based coatings. Microstructure morphology of Ni-based coatings was observed with optical microscope and scanning electron microscope. Chemical composition of microstructure in different areas of cladding layer was completed with EDS energy dispersive spectrometer. Phase of the coatings was analyzed by combining X-ray diffractometer. Hardness of the coating cross-section was measured with HXD-2000TM/LCD microhardness tester. Pin-on-disk abrasion test was performed on MDW-100 abrasion machine to evaluate abrasion resistance of coatings. The Ni-based coatings treated by induction cladding were free from such defects as cracks and pores, and exhibited metallurgical bonding to substrate. The coatings were mainly composed of γ-Ni, Ni2B, CrB, Cr23C6, etc. TiB2 particles added did not decompose during the cladding process. With the increase of TiB2 addition, both hardness and abrasion resistance of Ni-based coatings gradually increased. Hardness of the coating with 15% TiB2 addition was the highest and its friction coefficient was the lowest. Compared with the TiB2-free coating, under the same wear conditions, hardness of the coating containing TiB2 increased by 15.88%, friction coefficient decreased by 16.5%, and wear loss decreased by 43.15%. The addition of TiB2 particles increased both hardness and abrasion resistance of the coatings. Meanwhile, the coating containing 15% TiB2 particles exhibits the best coating performance.
