以TiC/Ti-Ni-Si合金粉末为前驱体，采用激光熔覆工艺在TA 15钛合金基体上制备了TiC增强Ti-Ni-Si金属间化合物耐磨复合涂层，涂层组织为TiC均匀分布于Ti 2Ni 3Si-NiTi-Ti 2Ni多相金属间化合物基体中。采用光学显微镜（OM）、扫描电镜（SEM）、X射线衍射仪（XRD）和X射线能谱仪（EDS）对涂层的微观组织进行了分析。研究了激光熔覆TiC增强Ti-Ni-Si金属间化合物复合涂层的室温干滑动磨损性能。结果表明，TiC/（Ti 2Ni 3Si-NiTi-Ti 2Ni）金属间化合物复合涂层具有优异的耐磨性和粘着磨损性能。(C)2009爱思唯尔有限公司版权所有。
Wear resistant TiC reinforced Ti-Ni-Si intermetallic composite coating with a microstructure consisting of TiC uniformly distributed in Ti2Ni3Si-NiTi-Ti2Ni multi-phase intermetallic matrix was fabricated on a substrate of TA15 titanium alloy by the laser cladding process using TiC/Ti-Ni-Si alloy powders as the precursor materials. Microstructure of the coating was characterized by optical microscope (OM), scanning electron microscope (SEM), X-ray diffraction (XRD) and X-ray energy dispersive spectrometer (EDS). Dry sliding wear resistance of the laser clad TiC reinforced Ti-Ni-Si intermetallic composite coating was evaluated at room temperature. Results indicated that the TiC/(Ti2Ni3Si-NiTi-Ti2Ni) intermetallic composite coating exhibited excellent abrasive and adhesive wear resistance. (C) 2009 Elsevier B.V. All rights reserved.
