Use of Combined Methods of Successive Carburizing and Nitriding of Martensitic Steels in Low-Pressure Atmospheres

The paper discusses combined conditions of saturating martensitic steel with carbon and nitrogen using low-pressure atmospheres. The studied conditions include pre-carburizing, hardening heat treatment, and finishing nitriding, as well as pre-nitriding, subsequent carburizing, and heat treatment. Acomparative analysis of the properties of steels obtained under different combined conditions was performed.
