| 摘 要： | 以TiFe 粉和碳的前驱体(石油沥青) 为原料, 用前驱体碳化复合技术制备了Ti-Fe-C 反应喷涂复合粉末, 并采用普通火焰喷涂技术成功制备了TiC/ Fe 陶瓷金属复合涂层。研究了不同C/ Ti 原子比对反应火焰喷涂TiC/ Fe 复合涂层相组成、显微结构和硬度的影响。结果表明, 前驱体碳化复合技术制备的Ti-Fe-C 系反应喷涂复合粉末中C/ Ti 原子比是影响涂层相组成、显微结构和硬度的关键因素。C/ Ti 原子比不同, 涂层的相组成和硬度不同; 随着C/ Ti 原子比增大, 涂层中TiC 团聚富集区增大, 涂层的孔隙率也随之增大。

| Abstract: | Ti-Fe-C composite powders for Reactive Flame Spray (RFS)were prepared by precursor carbonization-composition process using ferrotitanium and asphalt as raw materials. TiC/Fe composite coatings were synthesized and deposited by RFS. The influence of C/Ti atomic ratio on the component, microstructure and hardness of the composite coatings was investigated. The results show that C/Ti atomic ratio has strong influence on the component, microstructure and hardness of TiC/Fe composite coating. The TiC aggregate size and porosity of TiC/Fe composite coating increase with the increase of the C/Ti atomic ratio. |
