Structure and Wear Resistance of Nitrocarburized Medium-Carbon Steels

The methods of optical and scanning electron microscopy are used to study the structure and phase composition of nitrocarburized layer in medium-carbon steels alloyed with manganese, chromium and nickel. Transmission electron microscopy is applied to study the structure of the heterophase zone and t...

Description
Summary:The methods of optical and scanning electron microscopy are used to study the structure and phase composition of nitrocarburized layer in medium-carbon steels alloyed with manganese, chromium and nickel. Transmission electron microscopy is applied to study the structure of the heterophase zone and to determine its phase composition. The wear resistance and the wear mechanism of steels of different alloying systems are determined.
