摘要: Abstract The paper refers to examination of corrosion resistance improvement aluminium based material subjected a sealing procedure. tests were carried out for non-sealed and sealed anodic coatings using both scanning microscopy electrochemical techniques. correlation between parameters (i.e. potential (Ecorr), current density (jcorr)) contact difference (CPD) was examined. It found that in the first approximation jcorr as well Ecorr change linearly with CPDav (average CPD). shown also, decrease an increase caused by oxidation can be explained oxide thickness. Further observed is related root mean square roughness and/or disappearance surface anisotropy.
