Abstract: results of pilot studies whenever possible uses of processes of vibration shock and wave technology when receiving an oxidic covering are given in aluminum alloys details. The technology of forming of an oxidic covering in the course of influence of the vibration shock and wave technology reflecting an entity of complex impact of mechanical and chemical components of process on forming of a surface layer of a covering is fulfilled. The mechanism of structural and phase impacts on a resource and quality of coverings is installed that allowed to determine consistent patterns of receiving qualitative layers of a vibration chemical and mechanical oxidic covering (ViHMOP) on micro / a nanolevel, the causing obtaining earlier unattainable quality and operational properties of a surface of the details made of aluminum alloys. Researches of morphology of a surface of ViHMOP at the nano level showed that the time is 66 nanometers thickness a cell of 600 nanometers consisting of 10 growth layers, at the same time profile shift on the course of rotation of a working environment is set. This structure of a covering promotes increase in corrosion resistance as there is no access of an aggressive environment to base metal. The mechanism of structural and phase influences, influence of granulometric characteristics and a dynamic status of the polymeric working environments used as the mechanical activator of chemical processes of drawing coverings is studied. The technological chemical solutions adapted to working conditions when receiving the combined chemical and mechanical oxidic coverings with the lowered maintenance of a kremneftorid of sodium and chromic anhydride are presented. As a result of a covering surface research with use of the scanning probe microscope it is established that the surface of an oxidic covering is not homogeneous and includes the elements which are in solution and in aluminum alloy composition
