or without chlorides, was investigated. It was found that with increasing pH of the solution the
open circuit potential becomes more negative. Analysis of the polarization curves recorded
in these experiments leads to a conclusion that anodic polarization behavior of copper
includes transition from active to passive region with two anodic current peaks that include
formation of Cu 2 O film and a film that contains Cu (OH) 2 and CuO. It was found that there …
