Abstract
Different processing issues dealing with plasma treatments for corrosion protection of metals are discussed. It is shown that plasma-deposited inorganic coatings cannot be enough to ensure optimum protection to metal degradation. In particular, designing a suitable plasma pre-treatment of the metal surface with the right feed gas can enhance the coating performance. The improvement due to pulsed mode deposition and hydrophobic layer coating are also discussed, leading both to one order magnitude increase in the charge transfer resistance with respect to continuous plasma deposited SiOx.
