Abstract

In this manuscript, our aim was to optimize the inhibitory performance of a pyridazine derivative against steel corrosion in 1M HCl solution. The inhibitor efficiency percentage depends on various parameters, such as inhibitor concentration, solution temperature, and immersion time. Using the Dohlert matrix and NemrodW software, we conducted a study to determine the most influential parameters affecting the corrosion phenomenon. We selected three parameters - inhibitor quantity, immersion time, and temperature - based on preliminary knowledge. We evaluated the inhibitory efficiency by analyzing potentiodynamic intensity-potential curves and discussing the results obtained. Experimental designs offer benefits such as a reduction in the number of tests and the detection of interactions between factors. By following the experimental design methodology, we aimed to determine the best conditions to obtain maximum inhibitor efficiency while reducing the number of tests required.
