Presentation by Dr. Volker Heuer, ALD-Vacuum Technologies GmbH, Hanau, Germany

GETPRO @ Expomaq, Léon (April 13 and 14, 2016)

The automotive transmission gear industry is continually challenged to produce high performance components in the most cost-efficient manner. In many applications the high demands regarding fatigue properties of transmission components can be reached only by the application of a customized case hardening. This case hardening process results in a wear resistant surface-layer in combination with a tough core.

The process of Low Pressure Carburizing (LPC) with High Pressure Gas Quenching (HPGQ) has been established in industry over recent years. Compared to the traditional process of Gas Carburizing with Oil Quenching, the LPC-process offers the following benefits:

  • reduced heat treat distortion,
  • excellent carburizing homogeneity,
  • avoiding intergranular oxidation (IGO) and surface oxidation,
  • shorter cycle times,
  • possibility to integrate heat treatment into the production line
  • clean surfaces of parts after heat treatment with an eco-friendly process.

In order to totally integrate heat treatment into the manufacturing line and in order to synchronize heat-treatment with machining, a new heat treatment cell was developed and successfully implemented into automotive transmission production.

Following the philosophy of „One Piece Flow“, this technology closes the gap between green and hard machining and opens the door for new production concepts.  These concepts lead to significant cost savings while improving part-quality at the same time.

Speaker:

Dr. Volker Heuer joined ALD-Vacuum Technologies GmbH in Hanau, Germany, in 1999 as a research engineer. He was involved in the development of Low Pressure Carburizing, Plasma-Carburizing and High Pressure Gas Quenching. Since 2007 he is the Director R&D for ALD Vacuum Technologies GmbH. He studied Metallurgy and Material science at RWTH Aachen Technical University in Germany and worked as a scientist for TU Freiberg Technical University in the department of Mechanical engineering and for Cambridge University (UK) in the department of Materials Science and Metallurgy.
