中文摘要利用激光熔覆技术在钛表面预置硅粉原位制备了 Ti5Si3 涂层. 用 XRD、SEM 和 TEM 分析了涂层的组成和组织结构. 在 UMT 摩擦磨损试验机上对 Ti5Si3 涂层的在不同载荷和不同滑动速度下的摩擦磨损性能进行了测试. 实验结果表明: 涂层的物相主要是 Ti5Si3 相和基材 Ti 相, 涂层的显微结构为球状和块状晶, Ti5Si3 涂层具有较高的显微硬度, 涂层截面的平均显微硬度约为 840 HV0.2, 是钛基材的 4.4 倍; Ti5Si3 涂层可显著提高钛基材的耐磨性能; Ti Si 涂层的磨损机理为磨粒磨损和粘着磨损.
英文摘要Using silicon powder as the precursor to improve the wear resistance of Ti5Si3 coating was in situ successfully synthesized on Ti substrate by laser cladding. Friction and wear behavior of Ti5Si3 coatings under different normal loads and sliding speeds wear test conditions were evaluated using a UMT-2MT friction and wear tester. It is found that the prepared coating is mainly composed of Ti5Si3 and Ti phases. The high resolution transmission electron microscopy results confirm further the existence of Ti5Si3 compound in the prepared coating. Ti5Si3 coating has spherical and block-like microstructure. The Ti5Si3 coating shows a high average hardness of approximately 840 HV0.2, which is about 4.4 times as that of Ti substrate. Tribological properties of the prepared Ti5Si3 coating were systematically evaluated. It is found that the Ti5Si3 coating can improve the wear resistance of Ti. The wear mechanism of Ti5Si3 coating is abrasive and adhesive wear when sliding against GCr15 steel ball under all wear conditions.
