Anodized aluminium and aluminium alloys — Measurement of wear resistance and wear index of anodic oxidation coatings with an abrasive wheel wear test apparatus

The wear resistance or the wear index of the layers of oxide near the surface, of the whole oxidation coating thickness or of any selected intermediate zone may be determined. The method is applicable to all anodic oxidation coatings of thickness not less 5 micrometres on flat aluminium specimens. It is not applicable to concave or convex specimens.
