摘要

通过激光熔覆技术在Ti811钛合金表面制备了Ti基复合涂层, 研究了涂层的物相组成、微观组织、显微硬度及摩擦磨损性能, 分析了TiB2-TiC复合镶嵌结构的形成机理。结果表明:涂层主要由增强相TiC和TiB2、金属间化合物Ti2Ni以及基底α-Ti组成; TiB2的(0001)面和TiC的(111)面之间的错配度仅为1.057%, TiB2可以作为TiC最有效的异质形核的核心, 形成TiB2-TiC复合结构; 弥散强化、固溶强化和细晶强化效应使得涂层的显微硬度可达617 HV, 为Ti811钛合金的1.62倍; 涂层具有良好的摩擦磨损性能, 磨损体积、磨损深度和平均摩擦因数分别为175×10-3 mm3、80.13 μm和0.39, 磨损体积较基体约下降了26%。

Abstract

Ti-based composite coating is successfully fabricated on Ti811 titanium alloy surface by laser cladding. The phases, microstructures, microhardness, friction and wear resistance of the coating are studied, and the formation mechanism of TiB2-TiC composite mosaic structure is analyzed. The results show that the main phases of the coating are reinforced phases of TiC and TiB2, intermetallic compound Ti2Ni and matrix α-Ti. The misfit between the (0001) face of TiB2 and the (111) face of TiC is only 1.057%, which indicates that TiB2 can be the most effective heterogeneous nucleation core of TiC to form a TiB2-TiC composite structure. Due to dispersion strengthening, solid solution strengthening and fine-grain strengthening effect, the microhardness of the coating can reach 617 HV, which is 1.62 times that of Ti811 titanium alloy. The coating has good friction and wear resistance, its wear volume, wear depth and average friction coefficient are 175×10-3 mm3, 80.13 μm and 0.39, respectively, and the wear volume of the coating is about 26% lower than that of the substrate.
