Enhanced corrosion resistance of anodic non-porous alumina (ANPA) coatings on aluminium fabricated from mixed organic-inorganic electrolytes
A promising approach to fabricate protective Anodic Non-Porous Alumina (ANPA) coatings is developed through anodization of Aluminium in a mixed electrolyte comprising sulphuric acid and ammonium oxalate (AO). Under optimized conditions, a mechanically-stable ANPA coating with high corrosion resistance results. Growth kinetics, surface characteristics, phase constitution, composition of elements and electrochemical corrosion behavior are evaluated by SEM, EDS, AFM, XRD and electrochemical studies. As assessed by Electrochemical measurements, ANPA resists corrosion nearly 100 times than that of pure Al.
