Distortion of Gears due to Induction Hardening with the Gap-to-Gap Technique Open
This paper provides insights into the type and severity of gear distortions on each tooth during gap-to-gap hardening. The study compares distortions in gears from different manufacturing processes post-induction hardening and conventional…

Effect of alloy-specific case-hardening layers on the grindability of gears Open
Previous studies have already demonstrated a clear influence of the different subsurface microstructures resulting from variations in case-hardening on machinability during gear grinding. However, the impact of the alloy system has not yet…

Hydrogen Absorption during Case Hardening of Steels EN20MnCr5 (SAE5120) and EN18CrNiMo7-6 (SAE4820) Open
Damages to case-hardened components are often associated with the phenomenon of hydrogen embrittlement due to their specific fracture pattern. In the present work, the effects of the case hardening process on the hydrogen content in the ma…
