According to recent research from Manchester, the United Kingdom, "Improved methods are presented for investigating the flow of anodic alumina during the formation of porous anodic films on aluminium in phosphoric acid. In particular, the use of tungsten nanolayer tracers with increased flatness is shown to result in enhanced definition of the influences of flow on the tracer distribution, as observed by electron microscopy."
"Additionally, taper sectioning of films, by ultramicrotomy, and parallel sectioning of films, by sputtering using an Ar+ ion plasma, enable tungsten distributions across cells to be determined. In the case of an Al-3.5 at.%W alloy, the flow ...
