Methods of Modifying Anticorrosive Protective Properties of Silane Films

Abstract

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.

Corrosion Barrier Coatings: Progress and Perspectives of the Chemical Route

“…Here, further discussion is not necessary. The reader can refer to the references regarding the beneficial effects of cerium on CBCs [109,110].…”

“…Especially, amorphous nanoparticles such as CeO 2 have shown improved performance against corrosion via pore-clogging, and by filling gaps and imperfections of the coatings [131][132][133][134]. Their presence in the coating leads to avoidance of crack formation, yielding higher mechanical durability and anticorrosion protection [109,135]. CeO 2 is very stable in alkaline pH.…”
