| Popis: | The hydrogen permeation behavior of X65 steel was studied in a simulated Canadian groundwater (NS4) using a Devanathan-Stachurski cell. In the absence of a palladium coating on the detection side of the steel membrane, the hydrogen permeation current was suppressed by the growth of an oxide film on the steel. When a palladium coating was applied it was necessary to first remove the air-formed oxide from the steel surface which would otherwise control the permeation behavior due to its low hydrogen diffusivity. On the charging side of the membrane the deposition of CaCO3 and Mg(OH)2 enhanced hydrogen absorption into the cell leading to an enhanced permeation current. |
