From: Novel anodic oxide film with self-sealing layer showing excellent corrosion resistance
Surface morphologies and microhardness of SAOF and PAOF corroded with different SST time, (a1 and a2) 0 h, (b1 and b2) 400 h, (ca and c2) 800 h, (d1 and d2) 1200 h, (e1) 1600 h, (f1) 2000 h, g1 and e2 showed microhardness decreased with time.
