<p>A surface-coated aluminum material having improved corrosion resistance comprises a base aluminum or aluminum alloy material having on at least one surface thereof an aluminum-manganese alloy coating with a coating weight of 0.1 - 50 g/m<2> which may be further coated with an oxide film or chemical conversion coating. The aluminum-manganese alloy coating has the composition: Al-aMn-bX-cY-dZ where a is 1 - 50 weight percent, b is 0 - 10 atomic percent, c is 0 - 3 atomic percent, and d is 0 - 5 atomic percent; X is one or more metals selected from the group consisting of Cu, Ag, Fe, Co, and Ni; Y is one or more metals selected from the group consisting of Mg, Ca, Sr, Ba, Zn, Cd, In, Tl, Si, Ge, Sn, Pb, As, Sb, and Bi; Z is one or more metals selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, and Re; and Al comprises the balance of the alloy.</p> |
