摘要

A new method for increasing the wear resistance due to friction and at the same time to the abrasion and fatigue of the ferrous alloys, characterized in that the parts to be treated, after having undergone a previous immersion in a normal sulphiding bath, for steel or cast iron according to the class of alloy used, are subjected to a preheating by the weak flame of an oxyacetilºnico torch that raises the surface temperature around 250º.
