火焰喷涂合成技术是可用于制备金属陶瓷涂层的新技术该工艺的实施，需要对Ｆｅ－Ｔｉ－Ｃ系进行热力学分析，了解合成目标产物 Ｆｅ／ＴｉＣ的热力学条件通过利用计算相图技术计算 Ｆｅ－Ｔｉ－Ｃ系的相平衡及绝热燃烧温度 Ｔａｄ；重点讨论输入焓Ｈ（氧乙炔火焰功率）对体系Ｔａｄ的影响，结果发现，当Ｈ＝０时，满足体系自蔓延高温合成反应热力学条件的Ｆｅ含量＜５７（质量分数．％，下同）；在火焰喷涂合成过程中，输入焓的存在使体系满足热力学的条件放宽， Ｆｅ含量可高达 ８０．实验结果与计算结果吻合得较好．
Flame Spraying Synthesis Technology is a New Technology for the Preparation of Cermet Coatings The implementation of this process requires the thermodynamic analysis of the Fe-Ti-C system to understand the thermodynamic conditions for the synthesis of the target product Fe / TiC. By calculating the phase diagram of Fe -Ti-C system and the adiabatic combustion temperature (Tad). The effect of input enthalpy H (oxyacetylene flame power) on Tad was discussed. It was found that when H = 0, the system satisfies the thermodynamic conditions of self-propagating high temperature synthesis Fe content <57 (mass fraction%, the same below); In the flame spray synthesis process, the presence of input enthalpy to relax the system to meet the thermodynamic conditions, Fe content can be as high as 80. The experimental results are in good agreement with the calculated results.
