Abstract: 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.

Key words: reactive plasma spraying, metal-ceramic nanocomposite coating, iron-aluminum spinel, friction and wear
