alloy accelerates the chemical reaction causing a less satisfactory coating in terms of adhesion and corrosion protection. Chromate conversion coatings protect aluminum from oxidizing, thus these surfaces will have lower electrical resistance than un-protected aluminum.
Magnesium samples (4 × 4 in.) were ground down using 150-grit SiC paper so that the surface was flat. Samples were degreased with acetone prior to anodization. The anodizing cell consisted of an agitated bath with two steel hodes and anodization was conducted under constant current with a high voltage rectifier (70 A, 150 V) and the electrolyte temperature was maintained at 15 ± 5°C.
