摘　　要：随着船用燃机的高速发展,其热端部件的服役工况日渐严苛,而现有的热障涂层体系在耐多介质热腐蚀和高温热力耦合稳定性等方面均遇到性能提升瓶颈,无法完全满足新一代船用燃机热端部件更严苛的防护需求。对海洋大气环境下服役的热障涂层用陶瓷基材料的环境适配性改进研究现状进行了总结,分析了船用燃机热障涂层的服役工况特点,并对稀土离子掺杂改性与纤维增韧等手段强化的氧化钇部分稳定氧化锆陶瓷基材料,以及多种新型热障涂层用陶瓷基材料在提高热循环寿命及耐腐蚀性能方面的研究进行了归纳,最后预测了未来船用燃机热障涂层用陶瓷基材料的发展趋势。With the rapid development of marine gas turbines,the serve conditions of components in hottest parts are increasingly harsh.However,the existing thermal barrier coatings have actually fallen into the bottleneck of improving the multi-medium thermal corrosion resistance and high-temperature thermo-mechanical coupling stability,which can not fully meet the more stringent protection requirements of the heated end components for the new generation marine gas turbines.In this paper,the research status on the environmental suitability improvement of ceramic-based materials used in thermal barrier coatings under the marine atmospheric environment is summarized.The service condition characteristics of thermal barrier coatings in marine gas turbine are analyzed.In addition,the studies on the yttrium oxide partially stabilized zirconia(YSZ)materials strengthened by rare earth ion doping modification and fiber toughening,as well as various novel ceramicbased materials for thermal barrier coatings in improving thermal cycle life and corrosion resistance are summarized.Finally,the development trend of ceramic-based materials for thermal barrier coatings of marine gas turbines in the future is predicted.
