Abstract: 

Comparative tests on the oxidation of the samples austenitic stainless steel (18% Cr and 8% Ni) as received and after mechanical polishing in gases (technical argon and water vapor) and the coolant Pb-Bi. By conducting metallophysical studies have shown that mechanical polishing significantly reduces the rate of oxidation of the sample surface. This effect is particularly noticeable in the oxidation of steel in heavy coolant.
