Abstract

Corrosion never sleeps, therefore, industries rather than governments do their best to resist the different types of corrosion by all possible methods and techniques particularly in high-risk areas. Nevertheless, organic coatings are considered the most widely applied route for protection of metallic surfaces from corrosion and they are of a special importance in transport and infrastructure. Consequently, the main goal of this study is to provide a detailed overview of a protective pigment/inhibitor system based on boron phosphate and poly(p-phenylenediamine) as a new type of corrosion inhibitive coating that works holistically to obtain long-term performance for steel protection. However, characterization and investigation of boron phosphate and/or in-situ polymerized poly(p-phenylenediamine) were achieved via XRD, FT-IR, SEM and thermal analysis. Besides, different concentrations of boron phosphate/poly(p-phenylenediamine) were applied within controlled paint formulations based on epoxy resin, subsequently, they showed good physico-mechanical properties and high protection level against corrosion.
