The microstructure, chemical and phase composition as well as corrosion investigations of the (Mn-N-O-P) type surface layers in comparison to uncoated an aluminium alloy have been performed. An elaborated multiplex surface treatment of aluminium alloys enables forming of phase composition in the several zones of the (Mn-N-O-P) type layers.
