中文摘要利用激光熔覆技术在纯钛表面制备铁基涂层。用 XRD、SEM、TEM分析涂层的相组成和晶体结构。在UMT-2MT摩擦磨损试验机上对铁基涂层在不同载荷和不同滑动速度下的摩擦磨损性能进行测试。用SEM和3D表面轮廓仪分析铁基涂层磨损后的表面形貌和磨屑形貌。结果表明: 钛表面激光熔覆制备的铁基涂层的显微硬度约为860HV0.2, 具有优异的耐磨性能,磨损率为(0.70～2.32)×10-6 mm3/(N·m), 可以显著提高纯钛基材的耐磨性能;涂层的磨损机理为轻微的磨粒磨损和粘着磨损。
英文摘要Fe-based coating was produced on pure Ti substrate by the laser cladding technology. The composition and microstructure of the fabricated coating were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM) technique. The tribological properties were tested through sliding against AISI52100 steel ball at different normal loads and sliding speeds. Besides, the morphologies of the worn surfaces and wear debris were analyzed by scanning electron microscopy (SEM) and three dimensional (3D) non-contact surface mapping. The results show that the prepared Fe-based coating has a high hardness of about 860 HV0.2 and exhibits an average wear rate of (0.70–2.32)×10−6 mm3/(N·m), showing that the Fe-based coating can greatly improve the wear resistance of pure Ti substrate. The wear mechanism of the coating involves moderate adhesive and abrasive wear.
