ABSTRACT:
This invention relates to the use of low temperature plasma technology for significantly improved corrosion protection of steel. The plasma process involves pretreating of the steel surfaces by oxygen plasma and thin film deposition by polymerization of certain precursors on the steel. The process utilizes DC power, substrates as the cathode, magentron anodes, and system pressures of 0.01-0.5 torr. After the thin film plasma deposition it is also preferably to put a primer coating over the thin film.
