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.
