Rust Blame Cast on Electricity in Metal Corrosion
British chemist A R Evans at the International Congress of Pure and Applied Chemistry reports proof that rusting arises from electrochemical currents similar to those in a battery. He presents six measurement methods and an instrument to locate current sources and directions, identifying corrosion spots as anodes and noncorroded areas as cathodes or neutral zones.
