| 摘 要： | 研究以钛铁，石墨和纯铁粉为原料，用反应火焰喷涂技术制备TiC-Fe金属陶瓷涂层的耐磨性能，结果表明，涂层中富ＴiC和贫TiC片层的显微硬度分别达11．9－13．7GPa和3．3－6．0GPa，在SRV磨损试验机上经20min的干磨擦试验表明，反应火焰喷涂TiC-Fe涂层具有良好的耐磨性能，大约是常规火焰喷涂WC－Ni45金属陶瓷涂层的5倍，综合磨痕的轮廓曲线及其SEM形貌发现，其磨损机理主要是粘着磨损，但也有少量细小的硬质相相剥落。

| Abstract: | The wear resistance of TIC-Fe cermet coating prepaid by reactive flame spray of ferro- titanimu, graphic and iron powders was sutdied. It was revealed that the microhardness of TiC-rich and TiC- poor layer within the TiC-Fe composite coatings is 11.9-13.7 GPa and 3.3-6.0 GPa, respectively. A dry wear test showed that their wear resistance is five times higher than WC-Ni45 cermet coatings obtained by tradi- tional process. The major wear mechanisms are surface adhesion and a little stripping of TiC. |
