Results of experiment shows, that concentration of the hydrogen dissolved in the stainless steel type 304 after keeping in normal atmosphere is CH2 = 2*1019 at/sm3, instead of theoretically expected CH2 = 2*1019 at/sm3, similarly, for deuterium, dissolved at CD2 = 7*10-6Pa, its concentration, instead of theoretically expected C theorD2 = 8*1015 at/sm3 is CD2 = 1*1018 at/sm3. As for hydrogen also as for deuterium it is possible to explain their increased concentration by the relay dissociation of sorbed water The results show that the residual atmosphere of hydrogen or deuterium influences on ions exchange processes of deuterium and hydrogen in layers of sorbed water. So, in the submitted results it is enough 0,002% dissociation of sorbed water to ensure the pointed mentioned concentration. Experiment with the sample keeping (during 76 days) in the atmosphere of deuterium at pressure PD2 = 5*10-4Pa shows, that the maximal concentration of the dissolved deuterium is CD2 = 1*1018 at/sm3, that is about eight times less than expected theoretically. Concentration of the dissolved gases grows up to C maxH2 = 2*1021 at/sm3 and C maxD2 = 3*1019 at/sm3 as a result of mechanical action influence that corresponds to the 8,5% dissociation of H2O, and corresponds to 0,1% dissociation of HDO. So it was shown that the friction processes stimulates the process of sorbed water dissociation.
