<p>A method for making a thermal barrier coating (11), such as for gas turbine components (5) and mainly heat shields, combustion chambers or turbine wall covering panels, said thermal barrier coating (11 ) resulting from successive deposition of various numbers of layers (13, 15) which join together to form the coating (11 ), which coating (11 ) is obtained by any Thermal Spray process, including the steps of laying at least three coating layers (13), each of said layers being deposited at a different angle (t, ß, a) of the spray torch (33); said angles (t, ß, a) being defined relative to the surface to be sprayed and covering a range from 30° to 150° with respect to the tangent to the surface (3) of the component (5) to be coated. Protection also extends to the component so coated and the covering structure.</p> |
