As a new ternary material, the TiCN ceramic has attracted a lot of attention because of its advantages of high hardness, toughness, and wear resistance. Therefore, it has become one of the important materials to replace cemented carbides, such as WC-Co. Compared to bulk TiCN ceramic materials, TiCN ceramic coatings are easier to prepare and have excellent properties. Among the surface technologies used for the preparation of TiCN coatings, reactive plasma spraying can use the in situ reaction of inexpensive raw materials to synthesize TiCN coatings with high efficiency. However, the powder properties, spraying process parameters, and second phase additives significantly affect the performance of the plasma-sprayed ceramic coatings. In this work, the preparation of reactive plasma-sprayed TiCN coatings by different reaction systems, and the effect of parameter optimization and types of additives on the microstructure and properties of the coatings, were critically examined. Based on these studies, the trends and suggestions for future development of reactive plasma sprayed TiCN coatings are presented.

TiCN陶瓷作为一种新型三元材料，以其高硬度、高韧性、耐磨等优点而备受关注。因此，它已成为替代WC-Co等硬质合金的重要材料之一。与块状 TiCN 陶瓷材料相比，TiCN 陶瓷涂层更容易制备并且具有优异的性能。在用于制备 TiCN 涂层的表面技术中，反应等离子喷涂可以利用廉价原材料的原位反应来高效合成 TiCN 涂层。然而，粉末性能、喷涂工艺参数和第二相添加剂显着影响等离子喷涂陶瓷涂层的性能。在这项工作中，通过不同的反应体系制备反应性等离子喷涂 TiCN 涂层，并严格检查了参数优化和添加剂类型对涂层微观结构和性能的影响。基于这些研究，提出了反应性等离子喷涂 TiCN 涂层的未来发展趋势和建议。
