摘要：

The relationship between the amount of hydrogen electrochemically introduced to Pd and the volume and linear sizes of the formed PdH system, as well as the intensity of cavitation that arises after saturation of Pd with hydrogen, has been determined. The results of the study allows one to describe the mechanism of origin of cavitation on PdH in spite of the impossibility to determine the composition of atmosphere in bulk defects (microvoids, microcracks, and dislocations), which are formed upon hydrogenation of Pd. A Harvey-Knapp model has been employed, which describes well the origin of cavitation on nonwettable surfaces with fine cracks. The model is based on the hypothesis that presence of cavitation cores are present in water in the form of fine air bubbles.
