摘要：

采用WC(含碳量0.1wt%)、Ni、Si混合粉末为原料,利用激光合金化技术在TC4钛合金表面原位制备了含WC、Ni、Si的涂层,使用扫描电镜(SEM)、X射线衍射(XRD)与能谱分析(EDS)等方法分析了涂层的组织与成分,用HXD-1000B型维氏显微硬度计和MMW21型立式万能摩擦磨损试验机测试了涂层的显微硬度及摩擦磨损性能。结果表明:利用优化后的激光合金化参数制备出的含WC量较多的涂层,其整体均匀致密、无裂纹,且与TC4合金基材呈冶金结合;涂层物相主要由α-Ti、Ti₅Si₃、WC和TiNi组成;涂层硬度为950 HV0.2,平均摩擦因数为0.2,平均磨损量为0.308 mg,耐磨性显著提高。

Abstract:

Mixed powder of WC(with 0.1wt%C), Ni and Si was used as raw material, and the coating was prepared in situ on the surface of TC4 titanium alloy by laser alloying technology. The microstructure and composition of the coating were analyzed by means of scanning electron microscope (SEM), X-ray diffraction (XRD) and energy spectrum (EDS). The microhardness and friction and wear properties of the coatings were measured by HXD-1000 Vickers microhardness tester and MMW21 vertical universal friction and wear testing machine. The results show that the coating with higher WC content prepared by optimized laser alloying parameters is uniform and compact, no crack is observed, and is metallurgical bonding with the TC4 alloy substrate. The phase of the coating is mainly composed of α-Ti, Ti₅Si₃, WC and TiNi. The hardness of the coating is 950 HV0.2, the average friction coefficient is 0.2, the average wear loss is 0.308 mg, and the wear resistance is remarkably improved.
