Gas Flow through Metals

It has also been found(2,5,7, io,n,i2) that hydrogen gas in nascent form can penetrate metals such as palladium, iron, or nickel at room temperature, if the metal is made the cathode during electrolysis or if the hydrogen is generated by chemical reaction at the surface. Pickling a metal in hydrogen in this 

Before discussing the experimental data upon the permeability of metals to gases it will be of advantage to consider the cognate subject of gas solubility in metals. The differences in behaviour met with there may be reflected in the permeabilities (P), since the latter are defined by

In the previous chapter were considered the main phenomena of gas flow through metals. It was shown there that the gas flow (P) is governed by the equation...
