Abstract
We study the influence of preliminary electrolysis of the hydrogenation solution on the absorption of hydrogen by 65G steel. We establish that, in order for a hydrogenation solution to reach a stable active state, it is necessary that at least 0.1 A·h/liter of electricity pass through this solution. For activated and fresh solutions, the diffusion coefficients are found from plots of logi e-t. By integrating the functionsi e=f(t), we determine the amount of hydrogen that was extracted from steel for various hydrogenation times. The influence of nickel and palladium protective layers on the absorption of hydrogen by 65G steel is examined. It is discovered that the palladium protective layers facilitate substantial hydrogenation of the base metal.
