A kinetic study on the growth of porous anodic Al,O, films on Al metal, anodized galvanostatically at current densities 5-75mAcm-' in a stirred 15% w/v H,SO, bath solution at bath temperatures 204OYZ, was performed. A strict kinetic model was formulated which was, nevertheless, rather complex. There

The mechanism of growth of porous anodic AI,O, films at various bath temperatures, current densities and H,SO, concentrations was studled for tiims produced in a vigorously stirred bath at anodization times higher than those at which the maximum pore diameter behind or at film surface approaches fir
A strict kinetic model, governing the growth of porous anodic 01 2 0 3 films, was developed in a form easily and directly applicable to a galvanostatic anodization in a stirred bath at constant temperature . It was applied to the experimental results obtained from film growth at 25 ยฐC, 1SmAcm -2 and
