Traditionally phosphorous based corrosion inhibitors are applied to prevent corrosion occurring in heat exchangers of cooling tower operations. It is well known that a protective coating rich in phosphate material with significant thickness in micrometer range is formed and protects the surface of being corroded. Although efficient in corrosion prevention there is detrimental environmental impact due to discharge of phosphorous downstream of application. Significant research is sustained to design and identify alternative chemistries to address these concerns. A novel corrosion inhibitor was designed and successfully applied in the field. Since this novel chemical approach was pursued an extended understanding of the inhibition mechanism was needed. In this paper a combination of electrochemical and surface studies was used to shed light upon the mechanism through which the novel corrosion inhibitor reacts on the surface. X-ray Photoelectron Spectroscopy (XPS) was used to study the protective coating layer at the surface. This study focuses on understanding the impact of reaction time and flow regime on protective coating formation and composition. The XPS results will be correlated with the corrosion rates obtained via the electrochemical data.

Key words: corrosion inhibitor, cooling tower, water treatment, electrochemical studies, XPS
