Promoting the effect of zinc‐rich epoxy via poly(aniline‐co‐anisidine)/iron waste composite on corrosion protection of steel
Source abstract
Abstract
Abstract The purpose of this article was to evaluate the performance of a poly(aniline‐co‐anisidine)/iron waste composite (COIW) as an anticorrosive pigment for primer coatings. A procedure was outlined to prepare COIW and evaluate its anticorrosive properties following the electrochemical behavior and corrosion test of the coated steel. Various zinc‐rich epoxy primers were formulated by replacing part of the zinc powder (ZP) pigment with COIW. In all formulas, the ratio of pigment to epoxy resin was fixed at 2. In the pigment mix, the percentage of COIW was ranged from 5% to 60% by weight to the ZP. The performance of the formulated primers was estimated by the salt immersion test and potentiodynamic polarization measurement (corrosion potential, polarization resistance, and corrosion rate essays). It was demonstrated that COIW is effective in protecting steel from corrosion when it is used in combination with ZP.
