Potentiodynamic, impedance measurements were carried out on 304 stainless steel in 0.5N, 1.0, 2.0 and 5.0 N H2SO4 solutions. X-ray photoelectron spectroscopic [XPS] studies carried out on 304 stainless steel in H2SO4 solutions revealed the existence of CrOOH, Cr2O3, -Fe2O3, FeOOH, Mn2O3, Mn3O4, MnS, Ni (OH)2, Ni2O3, NiO, sulphides. The passive film found to contain chromium oxide inner layer an...

As a process complementing conventional electrode reactions, ionic vacancy production in electrode reaction was theoretically examined; whether reaction is anodic or cathodic, based on the momentum conservation by Newton's second law of motion, electron transfer necessarily leads to the emission of original embryo vacancies, and dielectric polarization endows to them the same electric charge as...

The dependences of the protective properties anodic oxide coatings on AD31 aluminum alloy surface modified with nitrates magnesium, potassium, and some 3d-elements composition sealing solutions parameters finishing treatment were established by scanning electron microscopy, potentiodynamic polarization, electrochemical impedance spectroscopy, salt spray chamber tests. A mechanism formation duri...

Using nickel electrode as dyeing electrode, sodium carbonate fixing alkali and anodic region region, cotton fabric was electrochemically dyed by reactive blue X-BR under external DC power supply. By comparing the rate, fixation polarization curve evenness of two methods, it can be concluded that electrochemical effect on dye is far better than traditional method.
