This invention relates to a plasma process for improved corrosion protection of steel. The process involves pretreating a steel surface cathode (12) in a vacuum chamber (11) containing magnetron anodes (13). Plasma gas is fed through a line (15), both for pretreatment of the steel surface cathode (12) and for deposition of a thin film of organosilane, over which is applied a primer coating reactive with organosilane. |
