The Future of vacuum carburizing.

   The Future of vacuum carburizing

Aerospace and automotive specifications need to be reviewed in light of rapid developments underway with these new materials. Serious consideration must be given to the use of elevated temperatures above 1900oF (1040oC) for carburizing and direct quenching, to minimize cycle times and reduce carbon absorption without adversely affecting microstructure. Preoxidation treatments have been found to be unnecessary, and rules for the use of high gas pressure quenching need to be better established and realized throughout the industrial sectors. Once this is accomplished, vacuum carburizing technology offers almost limitless possibilities.
