Vacuum heat treatment and high pressure gas quenching
Vacuum heat treatment and high pressure gas quenching（《真空热处理及高压气淬》）By Jean Jaques Since, Olaf Irretier
This technical article reviews high pressure gas quenching technique
using different quenching processes for improvement of part quality, cost
and mechanical properties.
Gas quenching represents an environmental friendly alternative to commonly
used atmospheric oil quenching. ECM has developed innovative
quenching processes for quality and performance improvement on
finished parts in the automotive and gear industry. The goal is to reduce
the level of distortion as well as the increase of mechanical properties.
Industrial applications will be shown with detailed data. Explanations will
be given on improvements and manufacturing process cost savings.
These processes could be directly applied to existing processes for global
cost reduction and quality improvement or for future products which
need increased performance and higher levels of quality.
