Abstract: It is established that the working life of a Pt$_3$Zr intermetallic anti-emission coating is determined by the mutual diffusion of free platinum atoms in the substrate and atoms of the substrate material in the coating. A multilayer coating technology has been developed, according to which a sublayer of the substrate metal carbide is initially formed that provides a barrier for the interdiffusion of platinum and substrate material. It is shown that the presence of this barrier layer significantly increases the working life of the anti-emission coating.
