教师简介

孟国辉博士于2021年9月加入西安交通大学材料科学与工程学院焊接与涂层研究所热喷涂团队，先后任助理教授、副教授。孟国辉博士长期致力于燃气涡轮发动机与火箭发动机用热防护涂层的设计、制备、表征及使役行为研究。截至目前，以第一作身份在Corrosion Science、Surface & Coatings Technology、Journal of Materials Science & Technology等期刊发表SCI论文近20篇，总引用超1000次。主持国家自然科学基金青年科学基金及多项校企合作科研项目，研究结果已应用于燃气涡轮发动机及航天发动机关键热端部件的涂层设计与工艺优化。

Dr. Meng is an Associate Professor in the School of Materials Science and Engineering at Xi’an Jiaotong University. He received his Ph.D. in Materials Science and Engineering from Xi’an Jiaotong University in 2020. He joined the Thermal Spray Group in the Institute of Welding and Coating at Xi’an Jiaotong University as an Assistant Professor in September 2021, and was promoted to Associate Professor in 2025. Dr. Meng’s research focuses on the design, processing, characterization, and performance of thermal barrier coatings and protective coatings for gas turbine and rocket engines. Dr. Meng is the first author of nearly 20 SCI-indexed papers in leading journals such as Corrosion Science, Surface & Coatings Technology, and Journal of Materials Science & Technology, with over 1000 total citations. He currently leads several research projects, including the National Natural Science Foundation of China (Young Scientists Fund) and multiple industry collaborations. His research outcomes have been applied to the design and process optimization of protective coatings for key hot-section components in gas turbine engines and aerospace engines.
