Влияние режимов гибридной модификации сталей на их коррозионные свойства

Abstract

In this study, the corrosion resistance of 20X13 and 38X2MYA steel samples subjected to hybrid modification, which included plasma nitriding performed at 480 °C for 180 minutes and thermal chemical and electrochemical oxidation, were evaluated. As a result of corrosion tests, calculations of the corrosion rate for all studied samples and polarization curve were obtained. It was found that the sample after chemical oxidation for 90 minutes (4,07*10-3 mm/year, 4,01*10-3 mm/year) has the lowest corrosion rate, and the sample of electrochemical oxidation has the highest (7,76*10-1 mm/year, 4,67*10-1 mm/year)
