The surface of molybdenum changes significantly after the proton irradiation process. The sputtering of the surface leads to a substantial cleaning of oxides. It is also possible to reduce oxides in a hydrogen plasma. The surface of molybdenum becomes more uneven with the manifestation of the fine structure after treatment. Molybdenum is sputtering at the rate ~ 0.1 µm/hour at the temperature of 300 °C and an ion current density ~ 1.5 mA/cm². The hydrogen content near the surface of molybdenum practically does not increase after irradiation with protons. The content of hydrogen in molybdenum does not change in depth, it is constant before and after irradiation. Molecular hydrogen is not observed in the both samples. The masses numbers of metal atoms is observed, which are part of the stainless steel (12X18N10T) from which the substrate holder is made.
