The Electric Currents Flowing over Rusting Iron

摘要: THE electrochemical mechanism of rusting is generally recognised, but our knowledge the distribution and strength currents rests upon somewhat indirect methods. In corrosion a horizontal iron surface by filter-paper wetted with sodium bicarbonate solution, it has lately been found possible to study current flowing horizontally through paper without any interruption circuits. This accomplished shunting small fraction two non-polarising electrodes superficially oxidised copper surrounded soaked in same liquid separated waxed paper.
