Abstract

The formation of high-temperature oxidation-resistant coatings on niobium by multi-component activated diffusion alloying in vacuum is investigated. Thermodynamic calculations of potential chemical reactions that result in anticorrosive protective coatings are performed. Comparative tests of high-temperature oxidation resistance of niobium with protective coatings are conducted at 1700 °C in open air
