| Abstract: | This study extended the use of response surface methodology (RSM) to explore the experimental space, identify optimal conditions for deposition and drying, and assess factor interactions for zirconium conversion coatings on aluminium alloy 5754. Corrosion resistance in a dilute Harrison's solution was evaluated using a non-electrochemical drop test and electrochemical techniques. Surface analysis supported the electrochemical findings obtained with the chosen RSM conditions. Unlike zinc and cold-rolled steel, AA5754 exhibits heightened sensitivity to the interplay of pH, conversion time, and H2ZrF6 concentration, which is attributed to the presence of intermetallic particles governing cathodic reactions and the subsequent conversion processes. |
