Gear Hardness Technology - March/April 1992

The article "Gear Hardness Technology" appeared in the March/April 1992 issue of Gear Technology.

In a very general sense, increasing the hardness of a steel gear increases the strength of the gear. However, for each process there is a limit to its effectiveness. This article contains background information on each of the processes covered. In each section what is desired and what is achievable is discussed. Typical processes are presented along with comments on variables which affect the result. By reviewing the capabilities and processes, it is possible to determine the limits to each process.

heat treating, basics, gear fundamentals, through hardening, carburizing, nitriding, gas nitriding, ion nitriding, induction hardening
