For the purpose of minimising
changes in dimensions and shape, nitriding cannot replace case hardening
until the respective component has first been analysed and, if necessary,
supplementary field trials have been conducted as well. Two examples taken
from practice show that this substitution is in fact possible. Promising
results are obtained when there is close cooperation between the manufacturer
of the component, the materials expert, and the heat treatment provider.

The author
Dr.-Ing. G Liebmann was born in 1932 and studied materials
engineering as an external student at the Bergakademie Freiburg. In 1979
he received his doctorate at the same institute. Until 1991 he worked as
a research assistant at the material laboratories of VEB Carl Zeiss Jena
(now Jenoptik GmbH) where he ran the department for heat treatment. At
the end of 1991 he assumed the post of head engineer at Härterei Reese
Weimar GmbH & Co. KG, where he has been entrusted with confidential
duties since 1992. In 1996 he was elected to the managing board of AWT. |
