Abstract
Wires of german silver, eureka, copper and iron, from 0.12 mm to 0.20 mm thick, were immersed in sea water at 25°C; and the manner of their corrosion was investigated, by means of tensile tests, carried out before and after moderate time elapses of immersion. In all cases, the corrosion took place in one mode;in the beginning very slowly, but,in course of time,with monotonous acceleration to the end. This mode of progress do not permit to assume that the reaction zone would propagate with a constant velocity through the substance. The cause of this phenomenon is discussed, and as a conclusion, it is attributed to the heterogeneity of distribution of the “chemically singular points”, caused by the heterogeneous plastic flow which occurred in the interior of the wires when drawn.
