Novel environment friendly corrosion inhibitor pigments based on naturally occurring clay minerals (original) (raw)

This research introduces novel, environmentally friendly corrosion inhibitor pigments derived from cerium (III) and calcium (II) cation exchanged bentonites. The study demonstrates that these pigments provide effective cut-edge corrosion resistance when used in organic coated galvanized steel, outperforming traditional pigments like strontium chromate and commercial calcium exchanged silica in terms of anti-delamination performance. The findings indicate that these bentonite pigments could serve as sustainable alternatives in corrosion protection applications.
