Oxidation and Hot Corrosion Behavior of Thermal Barrier Coatings-A Brief Review
Oxidation and hot corrosion occur on metallic parts of gas turbines on account of exposure to high temperature. Thermal barrier coatings (TBCs) are used to protect gas turbine components made of Ni-based superalloys from high temperature oxidation as well as hot corrosion. The stability of coated metallic gas turbine components is higher than that of non-coated ones. Suitable coating is crucial for obtaining higher turbine inlet temperature. However, the problem of conventional TBC system is the failure of yittria-stabilized zirconia (YSZ) top coat due to formation of thermally grown oxide (TGO) layer between the bond coat and YSZ top coat. The TGO formation should be properly controlled in order to prevent the spallation of the top coat. In the current review paper, an attempt has been made to focus oxidation and hot corrosion behavior of conventional thermal barrier coatings applied on gas turbine components for increasing the efficiency of gas turbines.
期刊介绍：
Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
