FIELD: methods of production of antiemission coatings.
SUBSTANCE: the offered invention is pertaining to formation of coatings and may be used for production of antiemission coating on grids of powerful oscillating tubes. The offered method includes formation of a layer of the tube grid material carbide, application of a layer of zirconium carbide from a metallic plasma of the vacuum-arc discharge at the temperature of the grid above 300°C, formation of shaping of a surface layer of platinum and an annealing. The technical result of the invention is development of a method of production of the intermetallic antiemission coatingPt3Zr having improved operational features.
EFFECT: the invention ensures production of the intermetallic antiemission coating with improved operational features.
