In many applications the high demands regarding fatigue properties of transmission components can be reached only by the application of customized case hardening. This case-hardening process results in a wear resistant surface layer in combination with a tough core. However, as a side effect, the components get distorted during heat treatment. This distortion has a significant cost impact because distorted components need to be hard machined after heat treatment.

IntroductionDistortion control is one of the major challenges in modern manufacturing. Distorted gear components cause noise in the transmission and may even create problems during transmission assembly. Especially battery-operated electric vehicles (BEV) and other electrified vehicles (such as Hybrids) require a low-noise transmission with high-precision components. Distortion has a strong cost impact because distorted components often need hard machining after heat treatment.
