Abstract The effect of deformation-oxidation activation of the surface layer on the kinetics of gas nitrocarburizing was investigated. It was found that preliminary plastic deformation of steel and surface oxidation lead to the acceleration of the gas nitrocarburizing. The dependences of the intensification degree on deformation level and oxidation temperature were studied. The optimal ranges of the deformation and oxidation temperature were determined. The predominant effect of intensification techniques at the stage of the chemical- thermal treatment was assessed. Reasons for the acceleration of gas nitrocarburizing are discussed.
Keywords plastic deformation, oxidation, activation, steel, nitrocarburizing, acceleration, chemicalthermal treatment, intensification
