Abstract Scope |
This research is focused on studying the corrosion behavior of Al-Ce alloy. The specimens underwent corrosion at different concentrations of NaOH and HCl aqueous solutions. To analyze such corrosion behavior, this research attempted to assess the mechanism that governs the process as it evaluates the effect on the surface microstructure. The parent alloy was prepared using pure aluminum and an Al-16wt.%Ce master alloy, melted at 760°C, and cast into a pre-heated copper mold. A water-cooled copper slab was placed over the melt and submerged into chilled water to attain fast solidification and to refine the microstructure. Then, the samples underwent corrosion at different times and concentrations of NaOH and HCl aqueous solutions. They were then characterized by optical-microscopy, x-ray diffraction, and electrochemical measurements. Preliminary results revealed changes in the open-circuit potential and the corroded alloy microstructure. |
