Abstract
The mechanism of deposition was investigated using maleic-linseed oil as a sample. The deposition was made by a constant voltage or by continuous pulses with high voltages, and the initial current-time relations were observed by means of a synchroscope. When we applied pulses with α⁄β values which were smaller than a value, the current decreased gradually after some time and a deposited film was found on the anode, but the decreases in the current was not found for a long time when the value of β was much larger than the value of α. The induction time was found from the current-time curve observed during a constant voltage deposition. These results were discussed from the standpoint that the deposited film is formed by coagulation resulted from ionic combination with hydrogen ions.
