Abstract
The influence of the regimes of separate stages of the mechanochemical treatment of the aluminum surface including degreasing of the surface with acetone; etching Al in a solution of sodium hydroxide; coarse grinding; chemical polishing in an alkaline glycerol-containing solution; fine grinding; finishing chemical polishing in an alkaline glycerol-containing solution is investigated. These pre-treatment steps allow to optimize the process of obtaining the necessary surface roughness for its subsequent electrochemical nanostructuring. Changes in the structure of the aluminum surface after each stage of preparation were controlled by optical microscopy. Obtained profilograms after the proposed processing of the surface of aluminum indicate getting the roughness parameters necessary for the subsequent nanostructuring of the surface by electrochemical anodizing.
