The procedure opens the possibilities to case-harden components without surface damage up to large CHDs: no surface oxidation, no manganese effusion, and no carbide precipitation. This automatically leads to higher component quality and in many cases surely to increasing component lifetime. Even the so possible elimination of the final hard machining of components can contribute to further increase of the efficiency.
This method was presented at the HK2012 in Wiesbaden in the presentation of Mr. Bischoff, et al.
