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 ３．３～６．０ ＧＰａ．在ＳＲＶ磨损试验机上经２０ ｍｉｎ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剥落．
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.
