Fluoride Ions Effect on the Corrosion Behavior of Pure Aluminum in Deaerated 0.05 M Sulfuric Acid Solutions

The corrosion study of aluminum-based materials is the topic a great scientific attention because increasing applications in many sectors these materials. fluoride ions (F−) effect on behavior pure aluminum deaerated 0.05 M sulfuric acid (H2SO4) solutions at 25 °C was investigated. electrochemical measurements such as open circuit potential and potentiodynamic polarization were accomplished to sulfate present test solutions. optical microscopic atomic force images taken view morphologies surface roughness which coincidence with rates found from immersion specimens using weight loss method. morphology elemental compositions evaluated by scanning electron microscope energy dispersive X-ray spectroscopy, respectively. results showed that general formed aluminum. It also revealed amount increased presence even very small
