On the basis of results of pulse – potentiostatic and pulse – galvanostatic methods of investigation of anodic dissolution of iron and steel in neutral chlorate solutions at pulse anode-cathodic treatment it is shown that depassivity of an anodic surface deals with: a) effect of mutual influence of processes, which take place during anodic and cathodic pulses; b) accumulation of chloride – ions, due to reduction of chlorate in a cathodic pulse. Owing to the above-stated effects the relation a c Q Q (values of charge in anodic and cathodic pulses), providing the greatest possible rate of dissolution, can achieve values 20–30 and more. It means at pulse anode-cathodic machining there is necessity of use of such parameters of pulses, at which the cathodic pulse will be utilized only as activating one (at a small value of a missed charge). |
