WebFor small-sized gears and sprockets, mode E is one of the most commonly used induction hardening methods. Because the teeth are all hardened, there may be some hardening cracks. And, in particular, by the impact load, there is a risk of brittle fracture in the fully hardened gear teeth.

Webinclusions can initiate fatigue cracks if they occur near the case/ core interface in areas of tensile residual stress (Fig. 2). Overheating gear teeth during operation or manufacturing (such as grind temper) can lower case hardness, alter residual stresses, and reduce resistance to subcase fatigue.
