High-temperature oxidation-resistant coatings on niobium and its alloys

The formation of high-temperature oxidation-resistant coatings on niobium by multicomponent activated diffusion saturation in vacuum is investigated. Thermodynamic calculations of potential chemical reactions that result in anticorrosive protective coatings are performed. Comparative tests of high-t...

Description
Summary:The formation of high-temperature oxidation-resistant coatings on niobium by multicomponent activated diffusion saturation 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.
