摘要
采用高速双丝电弧喷涂技术制备了含有非晶相的铁基涂层。对Fe_(55)Cr_(12)Mo_(10)Cu_2Y_2B_6C_(13)涂层的摩擦磨损特性及相关的力学性能:涂层显微硬度,与基体的结合强度和进行了测试分析。结果表明:①涂层摩擦因数低于基体材料Q235,磨损量也显著降低,涂层的磨损机理主要表现为剥离磨损。②涂层的显微硬度高于1000 HV,属于硬质涂层,涂层与基体的结合方式主要以机械结合为主。③涂层的力学性能随组织结构变化有起伏。
High velocity arc spray technique was utilized to spray iron-based coating contains amorphous phase. The friction behavior and related mechanical behaviors of the Fe55CrlEMo10CuEY2B6C13 coating were studied, including Vickers mierohardness （HV） and adhesion strength with substrate. The results are as the followsing： OThe friction coefficient of the coating is lower than that of substrate. The wear mechanism of the coating is mainly delamnation. ~The microhardness （HV） of the coating is about HV 1 000, which indicated it is hard coating. The adhesion between the coating and the substrate is mechanical bonding behavior.~The mechanical behavior of the coating is variational with the difference of the coating structure.
