Abstract Suspension plasma spraying (SPS) is ideally suited to produce porous or dense columnar, strain‐tolerant thermal barrier coatings (TBCs) and also offers the possibility of producing other microstructures such as feathery vertically cracked coatings. The specific properties TBC are significantly influenced by formed microstructure, that is, affected feedstock material process parameters. In this work, effects various parameters in SPS investigated. It was found suspension feed rate...
Columnar structured thermal barrier coatings (TBCs) have been intensively investigated due to their potential enhance the durability and reliability of gas turbine engine components. These consist vertically aligned columns that provide excellent resistance cycling. In this study, lifetime columnar suspension-plasma-sprayed (SPS) TBCs was evaluated using burner rig tests. The tests were carried out under high-temperature conditions. Significantly, pre-oxidation bondcoat during diffusion...
