| 摘 要： | 以钛铁粉、铁粉和蔗糖(碳的前驱体)为原料,采用前驱体热分解复合技术制备了Fe-Ti-C系反应热喷涂粉末,并通过普通等离子喷涂技术原位合成并沉积了TiC/Fe金属陶瓷复合涂层.利用XRD、SEM和EDS研究了喷涂粉末和复合涂层的相组成和显微结构.结果表明:前驱体热分解复合技术制备的Fe-Ti-C反应喷涂粉末粒径均匀,原料粉末颗粒间的结合强度高;所制备的TiC/Fe复合涂层主要由不同含量TiC颗粒分布于金属Fe基体内部而形成的复合片层叠加而成;TiC颗粒大致呈球形,粒径呈纳米级;TiC理论质量分数53%的TiC/Fe金属陶瓷涂层的耐磨粒磨损性能较好,SRV磨损实验中涂层的磨损面积为基体(45钢)的1/25左右.

| Abstract: | A kind of Fe-Ti-C composite powder for reactive spraying was prepared with ferrotitanium and sucrose as raw materials.TiC/Fe composite coatings were synthesized and deposited by reactive plasma spraying(RPS).XRD,SEM and EDS were employed to analyze the composition and microstructure of the composite powder and coatings.The wear resistance properties of the coatings were also tested.The results show that the particles of Fe-Ti-C composite powder for RPS are uniform without any impurity and the bonding streng... |
