Synthesis of plasma-polymerized toluene coatings by microwave discharge

الملخص EN

Plasma- polymerized coatings were successfully applied on aluminum alloy, AA2024, surface for corrosion protection.

The plasma polymerization pro cess was carried out by low pressure microwave plasma at room temperature.

The effect of microwave plasma power on the corrosion resistance of polymer coatings was investigated using the potentiodynamic polarization technique.

As the micro wave plasma power increased, the relative protective efficiency increased.

Polymer coatings on alloy surfaces suppressed both anodic and cathodic reactions.

The in crement in protective efficiency was due to a higher degree of cross-linking in the coating.

These findings suggest that the toluene polymer coatings provide a consid erable protection barrier for aluminum alloys.
