Formation of Manganese-Containing PEO Coatings on Aluminum Alloys

one process conversion coatings with developed surface and a high content of
manganese. The incorporation of manganese oxides into the composition of
Al 2 O 3 matrix contributes to the enhancement of catalytic activity of mixed oxide
systems.
2. The phase composition and morphology of mixed oxide covers surface have
been analyzed. The highly branched micro-porous and globular surface of
Al 2 O 3 ·MnO x coatings applied onto aluminum alloys is characterized by uniform
distribution of manganese which content reaches up to 36 wt%. The control of
composition and surface state of conversion mixed coatings has been achieved
by varying the PEO regimes.
3. The mixed manganese-aluminum oxide conversion coatings on the aluminum
alloys are characterized by a high corrosion resistance and catalytic activity.
Therefore, mixed oxide systems applied on the aluminum alloys are promising
in the environmental technologies for both air and water media purification.
