摘要

Procedures for obtaining the sulfo-nitriding of the ferrous or non-ferrous alloys and the sulfo-cementation of the ferrous alloys, in order to improve the wear resistance and the friction coefficient, characterized in that the parts to be treated are subjected to a current of gases composed of nitrogen and sulfur vapors.
