Abstract
In a method of producing on the surface of a component which consists of a titanium alloy or an intermetallic phase on the basis of titanium, a protective layer (according to the formula Ti5,0−xAgx+yAl3,0−yO2), a mixture of Ti powder and TiO2 powder, which has been sintered, is applied to the surfaces of the component or, if the titanium alloy includes 40-60 at % Al, a coating of silver is applied to the component and the component is then heat treated at 500 to 900° C. to form the protective layer on its surfaces.
Claims5
A method of producing on the surfaces of a component a protective layer having a composition according to the formula Ti5,O−xAgx−yAl3,0−yO2 with 0.5<x+y<1.0, said method comprising the steps of:
- providing a mixture of Ti and TiO2 powder and sintering the mixture in a vacuum so as to form a sintered powder from the mixture,
- mixing the sintered powder with Al and Ag and applying the mixture of the sintered powder and Al and Ag in a composition according to said formula to the surface of said component, and
- heating the mixture on said component to a temperature of 500 to 900° C.
A method of producing on the surfaces of a component, which consists of one of a titanium alloy and an intermetallic phase on the basis of titanium and has an Al content of 40-60at %, a protective layer having a composition according to the formula Ti5,0−xAgx+yAl3, 0−yO2 with 0.5<x+y<1.0, said method comprising the steps of applying a silver coating to the surface of said component and heating the component with said silver coating in vacuum or a protective gas atmosphere to temperatures above 700° C. to form said protective layer on said component.
