Influence of Microalloying on the Surface Layer of a Carbonitrided Steel 18CrNiMo7-6

, 2021
To further enhance the performance of case hardening steels, the surface layer is thermochemically treated. By carbonitriding, a thermochemical process by which carbon as well as nitrogen are brought into the surface layer, the tooth flank load capacity of case hardening steel gears can be dramatically improved in comparison to those elicited by ...
