中文摘要：

nanostructured 听涂层被喷洒的反应血浆制作，并且涂层的微观结构被 XRD， SEM 和 TEM 分析。结果证明涂层由锡和 Ti ₃ O 阶段，和涂层有典型喷洒的薄片结构。有粒子直径的 nanoscale 谷物不到 100 nm 被 TEM 在涂层观察，并且好 equiaxed 和圆柱的谷物在 nanostructured 听涂层同时被发现。而且，变丑双胞胎被 TEM 在涂层验证，它被高冷却率和不一致的温度分发在血浆喷气引起。

英文摘要：

The nanostructured TiN coatings were fabricated by the reactive plasma spraying, and the microstructure of the coatings was analyzed by XRD, SEM and TEM. The results show that the coatings are composed of TiN and Ti30 phases, and the coatings have the typical sprayed lamellae structures. The nanoscale grains with particle diameters less than 100 nm are observed in the coatings by TEM, and both fine equiaxed and columnar grains are found simultaneously in the nanostructured TiN coatings. Furthermore, the deformation twins are verified by TEM in the coatings, which are caused by the high cooling rate and the non-uniform temperature distribution in the plasma jet.
