On state-of-the-art aircrafts, ceramic matrix composites (CMC) will be used for turbine blades of engines.
In this case, environmental barrier coatings (EBC) are indispensable technology for suppression of steam oxidation of the CMC.
Therefore, the EBCs need very high oxygen permeability resistant property.
The candidate materials of the EBCs are some silicate ceramic materials. Suspension plasma spray (SPS) technique is suitable for making dense and stable silicate coatings.
Therefore, in this study, influence of spray conditions, especially substrate temperature etc., was investigated on suspension plasma sprayed silicate coatings was investigated.
And then, steam oxidation behavior, and mechanical properties were evaluated.
