This thesis focuses on the development and optimisation of zirconium conversion coatings (ZrCCs) on cold-rolled steel (CRS), zinc (Zn), and aluminium alloy AA5754 substrates through a multidimensional approach. The utilization of statistical tools, specifically response surface methodology (RSM), enabled the assessment of the individual and mutual effects of various parameters …
The inhibitory action of organic compounds, 2-mercaptobenzimidazole (MBI), octylphosphonic acid (OPA) and their binary combinations was studied on aluminium, copper and aluminium alloy (AA) 2024 in chloride environments by ex-situ conventional electrochemical methods and surface-analytical techniques. In addition, the influence of pre-treatment of the metal surface and the choice of …
