Abstract

The process of anodizing aluminium alloys in an ozone-containing electrolyte when a flat cathode is replaced with a needle shape was studied. The microstructure of the oxide layer and the density distribution of the phases in the volume of the film in two positions of the cathode — stationary and during its rotation — were investigated. The mechanical properties of the surface layer were determined
