Plasma polymerization has attracted considerable interest in the corrosion protection of metallic alloys. Plasma polymerized organic films were successfully prepared by plasma-enhanced chemical vapor deposition using toluene as the precursor. The protective abilities of toluene films as a function of toluene-Ar gas ratio in a 3.5 wt.% NaCl solution was characterized by the electrochemical method. The corrosion protective efficiency of plasma-polymerized toluene films increased with decreasing the toluene ratio (60-15%). Thus the corrosion rate of aluminum alloy coated with toluene films decreased. The highest protective efficiency was 65% at a 15% toluene ratio. This study shows that the toluene films have the potential to be used in corrosion protection applications of metallic substrates and their alloys.
