Thermal barrier coatings (TBCs) are generally used as a protective coating in gas turbine engine components in aerospace and aircraft industry [1]. Especially, TBCs applications used critical region parts exposed to high temperatures such as oxidation, hot-corrosion, thermal shock failures and CMAS (calcia–magnesia–alumina–silica) attack [2]. Volcanic ash degradation of TBC is a serious problem for many high temperature applications in aggressive environment such as turbine blades and vanes in gas turbines [3]. Impurities arising from the desert and volcanic environment dusts such as calcia–magnesia–alumina–silica (CMAS) formations cause degradation during the service conditions [4]. In this study, the effect of volcanic ash based failures were investigated and discussed in TBC systems.
