The efficiency of thorough anodic oxidation of ASTM A356 aluminum alloy as an alternative to painting its surface is studied. Microstructure, phase composition, and microhardness of oxidized layers of various thicknesses (45, 65, 80 and 90 mu m) are determined. Solid particle erosion tests are conducted in accordance with ASTM G76 and MIL STD 3033. It is established that with an increase in oxidized layer thickness aluminum alloy wear resistance is reduced and the surface roughness is reduced.
