Exchange by hydrogen and deuterium through the interface of contacting metals

The process of establishing a new equilibrium state, when metals are contacted mechanically, one of which is saturated with hydrogen (deuterium) and the other is not, has been studied. The transition to a new equilibrium state is related to the transfer of hydrogen (deuterium) from the metal with its excess to the non-saturated one. The rate of transfer and the amount of the transferred substance are determined by the type of the contacting pairs of metals and can reach 10% of the introduced hydrogen for 30 min of contacting.
