Gas quenching represents an environmentally friendly alternative to the more commonly used oil quenching. ECM has developed innovative "Step & Stop Quenching Processes" for quality and performance improvement on finished parts in the automotive industry. This study will focus first on the "Step Quenching Process". The goal of this process is to significantly reduce the level of distortion. The second focus will be on the "Stop Quenching Process" which is designed to increase mechanical properties. Some industrial applications will be shown with detailed data. Explanations will be given on why these improvements could be beneficial for 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.
New Vacuum Processes Achieve Mechanical Property Improvement in Gearbox Components
This paper introduces new process developments in low-pressure carburizing and carbonitriding using either high-pressure gas quenching or interrupted gas quenching.
(In this article, the interrupted gas quenching method used is StopGQ®, a registered trademark of ECM Technologies.)
Comparison of mechanical properties which result from each process will be discussed.
The reader will discover how the optimization of carbon and nitrogen enrichment and the mastering of gas quenching can improve fatigue strength and impact properties.
