..., particularly for large gears (over 508 mm, or 20 in., outer diameter) that normally exhibit high distortion if a case hardening process is used. An example for such an application is the internal ring gear of an epicyclic gearbox. These gears are usually designed with hardness in the range of 32 to 34 HRC...
