Abstract
The carburizing process has been used as surface hardening technology for many years. Carburizing process has been widely used mainly in the machine industry, and has resulted by the end of today.
Recently, the vacuum carburizing process has attracted attention not only as the conventional gas carburizing process but as a new carburizing method.
The vacuum carburizing process serves as environment-friendly equipment gentle also to people as compared with the gas carburizing process. And the validity can be found out now also about the difficult heat treatment technology by the conventional method.
This time, it introduces about the present condition and special carburizing technology of the vacuum carburizing furnace developed in our company.
