摘要：
The porous titania growth during electrochemical anodization of titanium films and foils in the 0.1 M ammonium fluoride (FNH4) solution in ethyleneglycol has been studied in the temperature range from -5 degrees C to +20 degrees C. Titania films with a smooth tubular morphology was found to be formed at the electrolyte temperatures below 0 degrees C. The growth rate was as high as 1.5 mu m/min provided that the tube diameters were up to 300 nm and the film porosity was less than 1%. Porous titanium anodization at the electrolyte temperature of 0 degrees C and below induces formation of porous titania with a structure close to ideal packed hexagonal prisms with a smooth tubular surface. The mechanism of the appearance of such structure is discussed. (C) 2012 Elsevier B. V. All rights reserved.
