ABSTRACT
The article deals with the problem of increasing resistance to corrosion of steel 38KhVFuYA used for the production of critical engine parts by laser heat treatment. The technique of carrying out corrosion tests by weight and electrochemical methods and their results are described, a significant reduction in the corrosion rate of the steel under study after laser heat treatment is established, optimal values of the power density of laser radiation are determined to achieve the most effective anticorrosive protection.
