Process for forming a silicon containing coating on a metallic substrate, anti-corrosion treatment process

摘要

Process for forming a deposit containing silicon at the surface of a metal substrate, according to which the following stages are carried out, concurrently or successively: (1) subjecting the said surface to an electrical discharge with a dielectric barrier, (2) exposure of the said surface to an atmosphere containing a silicon compound in the gaseous state, the stages (1) and (2) being performed at a pressure higher than 10,000 Pa. The invention also relates to a process for the anticorrosion treatment of a metal substrate, as well as to a metallised polymeric support.
