Abstract

A study of the distribution of species in a porous anodic film formed on a sputtered Zr-22 atomW alloy in a fluorideglycerol electrolyte is presented. The film consists of nanotubes within a fluoride-enriched matrix and forms with loss of ∼24 of the oxidized zirconium to the electrolyte. In contrast, loss of tungsten species is negligible, these species being retained in the nanotubes and separated from the pores by a tungsten-free region of the film material. The results suggest that the nanotubes are generated by the flow of material away from the nanotube base into the tube walls.
