Abstract

Manufacturing industries heavily depends on aluminum metal due to lightweight and good thermal properties. Aluminum (Al) is the most abundant metal elements in the crust. However, the low corrosion resistance limits the application in corrective environments. In this study, the electrochemical behaviour of superhydrophobic aluminium surfaces fabricated by nanosecond laser sources in a chloride environment was evaluated. Electrochemical behaviour was investigated using cyclic polarization curves and open circuit potential (OCP) measures. Cyclic polarization measurements were used to characterize the generalized and localized corrosion and OCP measurements are used to analyze the natural tendency of the material to be corroded. The superhydrophobic surfaces exhibited improvements in corrosion rate and polarization resistance due to an oxide layer formed during the laser treatment and the surface geometry itself.
