XMA and ESCA measurement was carried out for anodized films on Al-Mn alloy plates (99.99%Al+1%Mn). XMA plane analysis showed that Mn was dispersed like islands of which diameters were a few μm. ESCA spectra indicated that Mn peak shifted 2.6eV in the plus direction. It is possible that Mn is in an oxidized state (Mn(III)).
