Abstract
The method allows the production of a cermet coating which is composed of chromium carbide particles embedded in a nickel-chromium matrix, produced by thermal spraying on titanium alloys, which avoids the oxidation and the diffusion of oxygen therein at temperatures of up to 700° C. Additionally, a ceramic layer is deposited on the cermet coating which acts as thermal barrier.
Claims20
Method for the protection of titanium alloys against high temperatures, characterized in that it comprises the deposition of a cermet coating on the titanium alloy which avoids the oxidation and oxygen diffusion of said alloy at temperatures over 500°.
Material composed of a coating and a substrate characterized in that the coating consists of a cermet layer deposited on the substrate which is a titanium alloy with the special characteristic that the formation of an alphaα phase is not produced in the substrate interface, as a consequence of the deposition process of the cermet layer.
