| 摘 要： | 以TiFe粉和蔗糖为原料,通过蔗糖的热分解碳化制备Ti-Fe-C系反应热喷涂复合粉末,利用普通氧乙炔火焰喷涂成功制备出TiC/Fe复合涂层.采用XRD、SEM和TEM等对喷涂粉末和涂层的组织结构、涂层中的TiC颗粒进行了分析.研究结果表明:TiC/Fe复合涂层主要由TiC颗粒均匀分布于Fe基体中的复合强化片层构成,片层中TiC颗粒呈球形或近球形,粒径约为50nm;纳米级TiC颗粒增强的复合强化片层占涂层体积的60%以上.

| Abstract: | In this paper,TiC/Fe composite coatings were synthesized and deposited by reactive flame spray, using a kind of Ti-Fe-C composite powder prepared by carbonizing the mixture of ferrotitanium and sucrose as precursor. XRD,SEM and TEM were employed to analyze the microstructures of the composite powder and the coatings. It is showed that the composite coatings are mainly composed of composite layers,in which the TiC particles are dispersed within the Fe-alloy matrix,and TiC particles in these layers are spheri... |
