Abstract

Procedure to improve the corrosion resistance of a ferrous surface, characterized in that it consists of bringing the surface into contact with a composition that contains hexavalent chromium and conductive carbon in dispersed form, in a sufficient quantity to ensure the weldability of the treated surface, to a temperature not exceeding 50ºC.
