Abstract

Abstract In order to obtain predictable and reproducible properties from plasma-sprayed oxide coatings, it is required to control the spray parameters. In addition, powders should be chemically uniform so that reproducible particle melting can be achieved. Such melting behavior is obtainable from fused oxides. It is shown here for Al 2O 3-TiO 2 mixed oxides that fused powders can yield coatings with superior microstructures and improved industrially relevant properties.
