摘要

A novel potassium zinc phosphate (PZP) pigment was synthesized in the presence of benzotriazole (BTA) as a fourth generation of zinc phosphate (ZP). The corrosion inhibition properties of PZP-BTA, compared to PZP and ZP, were investigated by electrochemical techniques in the extract solutions. The chemical composition of the carbon steel surface immersed in different extract solutions was studied by scanning electron microscopy with energy dispersive spectroscopy. The corrosion protective performance of the epoxy coatings reinforced with 10 wt PZP-BTA and PZP was studied by salt spray test. Results showed superior performance of PZP-BTA in comparison to its former generation, i.e., PZP.
