Using diffusion welding under pressure of multilayer packages with a powder coating of molybdenum, tungsten and silicon, heat resistant multilayer composites ~35×40×2-3mm based on niobium with hardening niobium compounds with carbon and boron and heat-resistant coatings on the surface were obtained. Carbon in the Nb-alloy and coating fell from the CO-atmosphere in the chamber for welding and graphite gaskets located between the package and the punches.
