Thermal barrier coatings (TBCs) have beendeveloped to protect metallic and Si-based ceramic components from high temperature environmental attack and thermal stresses in structures and machine components across a wide range of industries and applications.Zirconia-yttria based oxides and (Ba,Sr)Al2Si2O8 (BSAS)/mullite basedsilicates have been used as the coating materials. There are several thermal barriercoating techniques with a objectives of reductionof maintenance costs, increase of the working temperature, reduction of thermal loads, resistance increase to erosion and corrosion and reduction of the high temperature oxidation. Thispaper incorporates a brief review on post researches on several recent activities in the field of modern TBCs, focusing on advanced coating techniques and in addition some advances coatings materials are described.
