Abstract
The results of pilot studies of the possible vibration shock and wave technology processes use when receiving an oxidic covering in aluminum alloys items are presented in the article. The technology of an oxidic covering forming in the course of the vibration shock and wave technology influence reflecting an entity of the process mechanical and chemical components complex impact on forming a surface covering layer is fulfilled. The mechanism of structural and phase impacts on a resource and quality of coverings that allowed to determine consistent patterns of receiving qualitative layers of a vibration chemical and mechanical oxidic coating on micro / a Nano level is installed, the causing obtaining the earlier unattainable quality and operational properties of a surface of the details made of aluminum alloys. The morphology researches of a vibrational chemical-mechanical oxide coating surface 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 the profile shift on the working environment rotation course is set. This structure of a covering promotes an increase in corrosion resistance as there is no access of an aggressive environment to the 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 the drawing coverings’ chemical processes 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 silico-fluoride of sodium and chromic anhydride are presented. As a result of the covering surface research with the scanning probe microscope use it is established that the oxidic covering surface is not homogeneous and includes the elements which are in solution and in aluminum alloy composition
