Ti_xCr_1-xN ceramic coating was prepared by reactive plasma spraying metal composite powders of Ti and Cr. The phase composition, microstructure, and hardness of the Ti_xCr_1-xN coating were investigated. The existing forms of Cr atoms in the coating were analyzed. Lattice structure and the elemental composition of the prepared Ti_xCr_1-xN coating were analyzed using TEM and EDS. The results revealed that Ti_xCr_1-xN coating fabricated on the basis of TiN had an FCC crystal structure with twin grains, the Cr atoms completely entered the TiN lattice when the Cr content was lower than 15 wt.%, and the solubility limit of Cr in TiN of 15 wt.%–20 wt.%. The microstructure of Ti_xCr_1-xN was the nanocrystal with a size range of 50–150 nm. The Cr atoms significantly enhanced the electron work function of the coating, improving its mechanical properties.

Ti _x Cr _1-x N陶瓷涂层是通过反应性等离子喷涂Ti和Cr的金属复合粉末制备的。研究了Ti _x Cr _1-x N涂层的相组成，显微组织和硬度。分析了涂层中Cr原子的现有形式。用TEM和EDS分析了制备的Ti _x Cr _1-x N涂层的晶格结构和元素组成。结果表明，Ti _x Cr _1-x基于TiN制备的N涂层具有双晶的FCC晶体结构，当Cr含量低于15 wt％时Cr原子完全进入TiN晶格，Cr在TiN中的溶解度极限为15 wt％ –20 wt。％。Ti _x Cr _1-x N的微观结构是尺寸范围为50-150 nm的纳米晶体。Cr原子显着增强了涂层的电子功函，从而改善了其机械性能。
