Abstract
The results show that plasma deposition of thin silica-based layer leads to degradation of the barrier properties of the coil-coating. The degree of the coating degradation strongly depends on the electrode location during plasma polymer deposition. The coil-coatings with plasma films deposited on the ground electrode demonstrated higher corrosion protection than the ones prepared on the powered electrode. The oxygen plasma activation of the coil-coatings before silica deposition leads to delamination of the top layer from the surface of the coil-coating during immersion in aqueous solutions. However, oxygen plasma post-treatment of the silica-based top layer tends to improve the barrier properties of the final system.
