CORROSION IX GENERAL Of the three principal theories of rorrosion: {\) the carbonic acid theory; (2) the hydrogen peroxide theory ; and (3j the electrolytic theory, the latter seems to fit all the facts most completely. W. H. Walker' gives the essential facts of the electr' tic explanation of corrosion as follows:— Every metal when |)laced in water, or under such conditions that a film of water may condense upon it. tends lo dissoKe in the water, or, in other words, to pass from its atomic or metallic condition into its ionic condition. This escaping tendency of the metals varies from that shown by sodium or fx)tassium, which is so jjreat as to cause instant and rapid decomposition of the metal and water, to gold or plitinum where such tendency to dissolve is zero. Between these twoextrcmes wo find the other common metals, including thereunder the element hydrogen, which may be considered as metal. At he ..torn of nietai passes into the water, it assumes a positive charge of electricity, leaving the met.illic mass from which it separated charged negatively; this property or escaping tendency of the metal is termed its solution ;>;essure. It is obvious, however, that this action can continue for only a short time; owir ■ .1 the fact that tlu mass pf metal and solution are of opposite polarity, the electrolvtic >cr,sion becomes so great that no more atoms can escape to the ionic state, and the solvent act'on ceases. This condition was first described by Helmholtz, and called by him an electrolytic double l;iyer. If now there be in the water ions of another metal which has a smaller solution pressure than the one under consideration, the action as above described will be reversed and the ion with the less solution pressure will pass back to the metallic state, plating out on the first metal and giving up its charge of electricity. At this point the first metal will be charged positively, .lud the solution in the immediate vicin- ity negatively, and there will tend to be set up a second electrolytic double layer opiX)site in polarity to the iirst. The result is, a current of electricity flows from the metal to the solution at the |)oiut where the metal passes into solution, through the solution to the metal at the point where the ions of the second metal are plating out, and back through the first metal to the starting point again. i'iie electn.lyiic double layers ale thus dt»lloycd, an electric current passes, and the solvent action of the water on the first metal continues. ' Journal of the Iron and Steel Institute, I'iW, Vol. I, p. 70. This pht-nomonon ,in.l ils rolalic.n to tlic corrosion of iron are clearly excmnlihcd in the well known Daniel or ^ravitv .ell.

In addition to the numerous corrosion experiments on discs of liie alloy al)<)Vf mentioned, there were atmospheric corrosion tests made on sheets of these alloys under service conditions. Pure cobalt of the analysis shown on pa^e 5 was sent from this hihor- atory to the American Rolling; Mill ("ompan\-, Middli'town, Ohio, I'arly in 191,?. It was arranged to make up charges in their four-ton exi)erinu'nt,d furnace, such as could l)e rolled into full-sizi'd rootinj; sheets to he suhjecti'd to the usual corrosion tests. Three such cohalt alloy sheets were sent to this laboratory, together with a run similarK' pri'pared, using monel metal in place of cobalt and a sheet of standard American ingot iron for com- parison. These sheets were M)" by 96" in dimension.-; and No. 26 gauge (00188" in thickness). All of these sheets were received in du()licale.

In gi'iieral. the corrosion of the allo\s formed by the addition of V ', of cobalt to American ingot iron, is about 75' ,' as great as that of the alloys formi'd by the addition of t)-.S', of cobalt. 5.

("{inclusions 4 and .S are, approximately, as true for the corre- sponding nickel alloys as for the cobalt allovs. There seems to be very little choice between the use of nickel and cobalt to form allovs with .American ingot iron containing between U-2S' i and ,?•()',' of the added metal for the prevention of corrosion.
