摘　　要：通过反应等离子喷涂技术制备含Ti含量不同的金属-陶瓷纳米复合涂层。并利用XRD和SEM对该涂层的物相组成、结构及形貌进行研究。结果显示,该涂层中形成了FeAl2O4、FexAly、TiO2、Fe相以及铁钛尖晶石相。对其力学性能的研究表明,随着Ti含量的增加显微硬度逐渐降低,磨损性能逐渐升高,当Ti含量为10%时,复合涂层的综合力学性能最优。Metal-ceramic nanocomposite coatings with different Ti contents were prepared by reaction plasma spraying. The phase composition,structure and morphology of the coating were analyzed by XRD and SEM. The results show that FeAl2O4,FexAly,TiO2,Fe phase as well as iron-titanium spinel phase are formed in the coating. The study of its mechanical properties shows that with the increase of Ti content,the microhardness gradually decreases,and the wear performance gradually increases. When the Ti content is 10%, the comprehensive mechanical properties of the composite coating are optimal.
