摘要：
The destruction of chromium oxides on the surface of 12Kh18N10T steel by concentrated ozone at different temperatures is investigated. The optimal temperature of the process in water is found to be 95 C. The oxidation time of the surface layer of chromium oxides is 5-10 min. Subsequent ozone treatment of a steel surface for a 20-fold longer time did not show any substantive destruction of the surface of corrosion-resistant steel. Ozone diffusion through the surface of a bubble to the metal surface plays a decisive role in the oxidation of chromium.
