Effect of Technological Parameters on Corrosion Resistance of Phytic Acid Coatings on 6063-Al Alloy

Abstract:

Phytic acid coatings were formed on 6063-Al alloy during immersion in phytic acid solution with various pH and phytic acid concentration for different time. The corrosion resistance of the coated samples was investigated using Tafel polarization technique. The results show that the effect of technological parameters on corrosion resistance of phytic acid coatings is great. With the increase of pH, the corrosion resistance of the coated sample is firstly increased and latterly decreased; it is optimum when pH was 3.0. The corrosion resistance of phytic acid coatings is increased largely with phytic acid concentration and immersion time. The anodic and cathodic corrosion processes of the coated 6063-Al alloy are inhibited markedly, and the corrosion current density is decreased for more than two orders of magnitude.
