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 ...

Calculation of sub-surface-initiated fatigue fractures in gears [PDF]

, 2019
Power-transmitting gears are typically heat-treated, most often case-hardened, to improve the fatigue strength and therefore to ensure higher fatigue life.

Growth of Subsurface Fatigue Fractures in Large‐Size Bevel Gears

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 2, Page 640-652, February 2026.
ABSTRACT Large‐size bevel gears are commonly used in marine industry for the applications of propulsion, such as azimuth thrusters. The gears are typically designed for specific use, as they are directly transferring power from one component to another.

Impact of various heat treatments on the microstructure evolution and mechanical properties of hot forged 18CrNiMo7-6 steel [PDF]

, 2017
Carburizing is a method of enhancing the surface properties of components, primarily made from low to medium carbon steels, such as shafts, gears, bearings, etc. Carburized parts are generally quenched and tempered before being put into service; however,

Fatigue strength evaluation of case‐hardened components combining heat‐treatment simulation and probabilistic approaches

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 3, Page 745-765, March 2024.
Abstract In order to raise the hardness and strength of the surface layer of mechanical components and induce favorable residual compressive stresses, case‐hardening procedures have become established in the heat treatment of steel. In this work, a calculation concept for the fatigue strength of components that have been case‐hardened through ...
