[目的]研究WC–10Ni5Cr与Cr3C2–25NiCr涂层的耐磨性能。[方法]采用超音速火焰喷涂技术在ZG0Cr13Ni5Mo高强不锈钢表面制备了WC–10Ni5Cr和Cr3C2–25NiCr金属陶瓷涂层，考察了涂层的孔隙率、显微硬度及摩擦磨损行为。[结果]两种涂层均呈现致密的金属陶瓷复合结构，组织结构致密且无明显层状特征。其中WC–10Ni5Cr涂层孔隙率较低(0.69%),Cr3C2–25NiCr涂层的孔隙率略大(0.93%)。WC–10Ni5Cr涂层和Cr3C2–25NiCr涂层的显微硬度分别达到1 253.3 HV0.2和1 121.5HV0.2，前者的耐磨性显著优于后者(与基体的磨损量比分别为1∶52和1∶30)。[结论]两种涂层均以磨粒磨损为主，但WC–10Ni5Cr涂层主要表现为切削犁沟和少量硬质相脱落，而Cr3C2–25NiCr涂层呈现周期性切削和硬质相疲劳破碎特征。与Cr3C2–25NiCr涂层相比，WC–10Ni5Cr涂层具有更优异的综合性能。
Abstract：[Objective] To study the wear resistance of WC–10Ni5Cr and Cr3C2–25NiCr cermet coatings. [Method] WC–10Ni5Cr and Cr3C2–25 NiCr coatings were deposited on ZG0Cr13Ni5Mo high-strength stainless steel by high-velocity oxygen-fuel(HVOF) spraying. The porosity, microhardness, and tribological behavior of the coatings were examined. [Result] Both coatings exhibited compact cermet composite structures without distinct laminar features. The WC–10Ni5Cr coating demonstrated lower porosity(0.69%) compared with the Cr3C2–25 NiCr coating(0.93%). The microhardness reached 1 253.3 HV0.2 for WC–10Ni5Cr and 1 121.5 HV0.2 for Cr3C2–25NiCr. The wear resistance of WC–10Ni5Cr was significantly superior, with a wear loss ratio to the substrate of 1:52, versus 1:30 for Cr3C2–25 NiCr. [Conclusion] Both coatings primarily underwent abrasive wear. The WC–10Ni5Cr coating displayed plowing grooves with minimal hard phase detachment, whereas the Cr3C2–25NiCr coating exhibited periodic cutting and fatigue-induced fragmentation of hard phases. The WC–10Ni5Cr coating possesses superior comprehensive performance to the Cr3C2–25NiCr coating.
