“…The results indicate that potassium permanganate would be a promising inhibitor for the silane film system and could have wide applications with its low price and high efficiency. The results of many works confirmed that the addition of corrosion inhibitors to modify silane coatings is beneficial up to a certain amount [45,49,50,52]. It was verified that a higher than optimal corrosion inhibitor concentration in silane film caused a significant decrease in corrosion protection due to destabilization of the siloxane network.…”

“…The tendency of zinc cations to deposit as hydroxide and oxide on the cathodic zones is reported elsewhere [51]. The inhibiting and healing effects of potassium permanganate for silane films deposited on the AZ91D magnesium alloy substrate were evaluated by She et al [52]. Scanning electron microcopy observations coupled with energy dispersive spectroscopy analysis (SEM/EDS) confirmed that KMnO 4 formed manganese oxide/hydroxide precipitates and blocked further propagation of the corrosion process.…”

Due to the fact that it is highly toxic and carcinogenic, chromate-based surface treatment is restricted or gradually reduced in many countries. Among the alternatives to replace conventional chromate coatings, organosilanes show some important advantages such as competitive price and environmental compatibility. These substances inhibit the corrosion processes of metal surfaces but cannot offer long term-protection. For this reason, silane films have been modified by different procedures. In this paper, methods of improving the anticorrosive protective performance of silane films have been presented.
