Abstract

Results of optimization of the composition and technology of depositing amorphous aluminosilicophosphate coatings for protecting niobium and niobium-base alloys from the action of oxygen of the ambient at an elevated temperature and the resulting loss of plasticity are presented. Forced and long-duration thermal tests of specimens with coatings have been conducted and proved the effectiveness of the designed coatings. Experimental data on temperature dependences of the thermal conductivity and the rate of loss of mass of the material of the coatings in vacuum are presented.
