CMAS dilemma in jet engines: beginning or ending?
Published as part of the Virtual Special Issue “Beihang University at 70”

Abstract
Jet engines are susceptible to contamination by environmental debris (volcanic ash, sand, and dust, called CMAS). When CMAS ash is ingested into gas turbines, it melts and can attach to hot components of the jet engines that may clog engine parts and damage protective ceramic thermal barrier coatings (TBCs). The engine’s performance may be impeded and can even cause catastrophic failure when this contamination is in excess. This research presents the current understanding of these CMAS challenges in nature and deposit-induced failure mechanisms of TBCs. The strategy mitigation of new functional TBCs to stop the wetting of CMAS explained the details of experimental and theoretical analysis of the melting and impacting processes of CMAS ash in jet engines.
