Заглавие : Anodic behaviour of the Cu82Al8Ni5Fe5 alloy in low-temperature aluminium electrolysis Место публикации : Corrosion Science. - 2013. - Vol. 70. - С. 194-201 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): анод--электролиз--растворение--электролит Аннотация: A Cu82Al8Ni5Fe5 wt.% alloy was evaluated as an inert anode in the electrolysis of an Al2O3-saturated, KF35.6–NaF12–LiF3–(AlF3)49.4 melt (790 °С) for 73 h. It was shown that metal consumption at the alloy/scale interface led to the formation of a ring-like gap that was filled with oxygen-free electrolyte. It was hypothesised that the electrochemical transfer of the alloy components through the gap occurred and the chemical oxidation of the alloy particles after the dissolution-deposition process took place in the scale. It was concluded that the rate of scale formation was governed by the percentage of current that had passed through the gap Доп.точки доступа: Khramov, А. P. ; Kovrov, V. A.; Zaikov, Y.
