The morphology of titanium dioxide and titanium dioxide-tungsten trioxide nanocomposite films fabricated by anodizing in a glycerol solution containing 0.13 M NH4F and different quantity of Na2WO4 was investigated as a function of sodium tungstate concentrations. The effects of sodium tungstate concentration on the surface morphology were observed by scanning electron microscopy (SEM). It was c...

Anodizing is an electrolytic coating process that converts aluminum into oxide. The anodizing widely used in the manufacturing industry, especially automotive components. Its utilization has benefits such as resistance to scratches, ease of maintenance, and added decorative value. purpose this study was determine effect time variations on hardness thickness oxide layer 6xxx series processes. va...

Abstract The presentation gives an insight into the fascinating world of anodizing as corrosion protection but also goes far beyond. Starting with introduction to formation anodic oxide films and their characteristic features, authors briefly outline subject pore nucleation growth. number, size, shape pores essentially determine properties play a crucial role in final application layers. tailor...

Titanium alloys are used in different industries such as biomedical, aerospace, aeronautic, chemical, and naval. Those have high requirements with few damage tolerances. The aim of this work was to study the corrosion behavior titanium anodizing non-anodizing alkaline (KOH NaOH) solutions, exposed 3.5%wt. NaCl 3.5% wt. H 2 SO 4 solutions at room temperature using cyclic potentiodynamic polariza...

Titanium oxide nanotubes were fabricated by anodic oxidation of a pure titanium sheet in an aqueous solution containing 0.5 to 3.5 wt% hydrofluoric acid. These tubes are well aligned and organized into high-density uniform arrays. While the tops of the tubes are open, the bottoms of the tubes are closed, forming a barrier layer structure similar to that of porous alumina. The average tube diame...

The aerospace industry mostly uses the aluminum alloys 2xxx and 7xxx series for their fuselage construction, some of them are assembled using structural bonding because it is strong, easy during fabrication process, resistant to corrosion, non-toxic. anodization process a proven surface treatment method bonding. Phosphoric Sulfuric Acid Anodizing (PSA) an eco-friendly alternative as chromate-fr...

The electronic properties of barrier and porous layers on Ti Ti6Al4V were studied. Barrier anodic oxides grown to 40 V are both n-type semiconductors with a band gap 3.3 eV 3.4 respectively, in agreement the formation amorphous TiO 2 . Anodizing 200 at 20 mA cm −2 calcium acetate β -glycerol phosphate disodium pentahydrate leads Ca P containing films photoelectrochemical behaviour dependent met...
