Abstract: The NiCrBSi powder, tungsten carbide powder and binder were proportionally mixed to prepare a flexible nickel-based tungsten carbide metal cloth through grinding, ball milling, and roll pressing. The flexible metal cloth was cut to appropriate dimensions and coated onto Q235 low-carbon steel surfaces, followed by vacuum brazing technology to fabricate nickel-based tungsten carbide wear-resistant coatings. The effects of different tungsten carbide contents (30% to 70%, mass fraction) on shear strength, coating hardness, and wear resistance were investigated. Results show that as the tungsten carbide content increases from 30% to 70%, the coating’s shear strength significantly decreases from 486.6 MPa to 8 MPa. Due to the insufficient metallurgical bonding strength between steel substrates and nickel-based tungsten carbide coatings with 60% and 70% WC (rendering them impractical for applications), the hardness and wear resistance of coatings with 30% to 50% WC were analyzed here. When the WC content increases from 30% to 50%, the average hardness of the coating’s hard phase layer increases from 817HV10 to 929HV10, representing 6—8 times that of the substrate. This demonstrates that tungsten carbide particles significantly enhance coating hardness as a hard phase. Additionally, the friction coefficient decreases from 0.5 to 0.44, while wear loss reduces from 0.005 2 g to 0.002 4 g, indicating that tungsten carbide effectively improved wear resistance by providing substantial load-bearing and anti-wear effects during abrasion. Therefore, the coa-ting achieved optimal hardness and wear resistance with 50% WC content while maintaining relatively high shear strength. The findings provide critical insights for optimizing wear-resistant coating design and industrial applications.
