Abstract

A process of applying a coating to a substrate is provided. A layer of a ceramic material is applied on the substrate by a thermal spray process. The layer is then subject to plasma electrolytic oxidation (PEO) processing to densify the layer such that a porosity of the layer after PEO processing is lower than a porosity of the layer before PEO processing, or modify the layer by incorporating additional ceramic phases from the electrolyte bath into the densified layer, or improve the adhesion of the thermal spray layer. A base layer may be applied to the substrate with PEO processing before the above referenced layer is applied and/or a ceramic topcoat may be applied to the above referenced layer by a thermal spray process.
