Object: the structure and characteristics of stainless steel and duralumin surfaces. The purpose: an establishment of the basic laws of physical processes and their mechanisms on a surface of stainless steel and duralumin under the influence of an irradiation by ions of hydrogen on the base of created in work experimental spectral ellipsometer. Methods: multiangular and spectral ellipsometry, interferometry, auger spectroscopy, scanning electronic microscopy, a method of diffraction of reflected electrons. Results: the experimental automated spectral ellipsometr for research of radiation transformations on a surface of metals and alloys is created. It is experimentally proved, that the bombardment of samples of mirrors from stainless steel by hydrogen ions leads to change of a surface structure: to removal of an strained layer and to the formation of step structure because of the different dispersion factor of grains with different orientation. It leads to falling of reflection factor. It is proved, that the erosion of polycrystalline stainless steel grains with different orientation is different under bombardment of stainless steel mirrors by hydrogen ions. For the first time it is experimentally proved, that mirrors from stainless steel with orientation <111> show the greatest resistibility to an irradiation by ions H3+ up to energies 1.5 KeV. The field of application: physics of a solid state, the radiation physics
