ABSTRACT:
Thermal-insulating material provided on a metal substrate by means of an EB-PVD process includes a metal having a substantially magnetoplumbitic crystal structure and having a chemical composition according to general formula: Ln3+M2+1+xQ44+A111−2xO19. The thermally-insulated metal substrate may advantageously include an adhesive layer provided between the surface of the metal substrate and the thermal-insulating layer. The process for producing the thermal-insulated metal substrate includes applying the thermal-insulating material onto a surface of the metal substrate employing an EB-PVD process.
