Nanoporous anodic aluminum oxide (AAO) has been used in many different fields of science and technology, due to its great structural characteristics. Solar selective surface is an important application of this type porous material. This paper investigates the effect of nanoporous AAO properties, including; film thickness, pore area percentage and pore diameter, on absorption spectra in the rang...

To improve the photocatalytic activity of titanium oxide, nanometer oxide powder was mixed with a phosphoric acid solution to form an electrolyte for preparing TiO2/Al2O3 coating on surface aluminum alloy. Hydrothermal technology has been used adjust crystalline structure oxide. Scanning electron microscope observe micromorphology anodic before and after treatment using hydrothermal technology....

We investigated film thickness effects of sulfuric acid anodized aluminum when galvanically coupled with carbon fiber reinforced plastic（CFRP）. The CFRP was electrically to alloys 1050, 5052, 6061, and 7075 in 3.5 wt.% NaCl solution at 35 ℃. Galvanic current passing from the 1050 6061 decreased as anodic oxide thickened. For galvanic between 5052 CFRP, elapsed time until corrosion density value...

We have presented a method to prepare a uniform anodic nanoporous oxide film on the surface of a cylindrical zircaloy (Zr) tube. The distribution of the electric field around the Zr tube determines the distribution of the thickness of the anodic nanoporous oxide film. The electric field generated when a cylindrical Zr tube is electrochemically anodized was simulated by using commercial code COM...
