Sažetak
This paper examines the strength, deformability, and load-carrying capacity of niobium-based alloys VN-3 and VN-9 (Nb-Mo-Zr-C), both in the initial state and with ceramic slip coatings based on molybdenum-hafnium silicides, under conditions of short- and long-term static tension in vacuum, inert medium, and in air in the temperature range from 1770 to 2020 K. A method has been developed to assess the damage accumulated in the niobium alloy/silicide-ceramic coating composite under high-temperature loading. As a result of studying the creep and long-term strength of the niobium alloy/silicide-ceramic coating composite, the values of 0, 5 % and 1, 0 % creep limits of the composites for test times of 0, 1 ; 1, 0 ; and 10 hours at temperatures of 1770 and 2020 K have been obtained.
