Abstract: To address the problem of insufficient wear and corrosion resistance on the surfaces of mechanical components. In this study, BN-modified Ni60-Cr3C2 coatings were fabricated using an ultra-high-speed laser cladding technique. The effects of BN on the microstructure and properties of the coatings were systematically investigated by X-ray diffraction (XRD), optical microscopy (OM), scanning electron microscopy (SEM), Vickers microhardness testing, friction-wear experiments, and electrochemical measurements. ?The results show that the Ni60-Cr3C2 coating is mainly composed of Cr3Ni2, Cr1.12Ni2.88, Cr7C3 and Fe3C. After the addition of BN, in-situ Fe2B, Cr2N, and Cr2B3 phases were generated, and BN further promoted the decomposition of Cr3C2 as well as the formation of Cr-rich dendritic networks. The structural uniformity and wear resistance were significantly improved, with its wear volume reduced by 53.3% compared with the Ni60-Cr3C2 coating. Moreover, BN markedly enhanced the corrosion resistance of the coating. The corrosion current density of the Ni60-Cr3C2-5%BN coating was 1.28×10-6 A·cm-2, 81.0% lower than that of the Ni60-Cr3C2 coating, and its charge-transfer resistance reached 5562 Ω·cm2, which is 2.2 times that of the unmodified coating.
