摘要
激光重熔是常用的一种提高等离子喷涂双层结构热障涂层性能的方法。综述了国内外相关研究进展,主要从重熔工艺的角度介绍了其主要制备技术,常规激光重熔强化,激光重熔分步强化和激光重熔一步强化加工方法。阐述了激光重熔等离子喷涂热障涂层存在的主要问题,同时指出了解决的主要措施,最后对其主要发展趋势进行了讨论。
The performance of plasma-sprayed double-layer structure thermal barrier coatings(TBCs)can be effective improved by laser remelting. The present situation of domestic and foreign researches on plasma-sprayed double-layer structure TBCs by laser remelting is reviewed. Conventional laser remelting, step by step strengthen processing and one step strengthen processing are three types of main processing methods. The major problems of laser remelting plasma-sprayed TBCs were introduced and its solving measures were also pointed out. Finally, the development trends were also discussed.
