A Critical Review on High Temperature Oxidation Performance of Coatings on Steel Substrate

Abstract

High temperature oxidation is a severe problem in high temperature application components such as Gas turbine blades, vanes, combustor cans, etc., in the power production industry. The main problem encountered in forming scales over the surface is that it further degrades. In recent decades, Cermet coatings have become very popular for many industrial applications due to their excellent physical, tribological, high temperature and mechanical properties. This review article suggests that by cermet coatings over the steel substrate may reduce the excessive formation and propagation of scale. Further, this can be used as a barrier to the diffusion/penetration of corrosive elements through coatings.The published work in the literature survey covers the period of past 20 years with main focus on the current trends.
