The aluminium sheet was then used as anode and a lead plate (3 mm × 40 mm × 40 mm) as counter-electrode in the electrochemical cell. The anodizing was run for 60 minutes in the galvanostatic mode (J a = 1.2 ± 0.1 A/dm 2) using a sulphuric acid solution (150 g/L) thermally regulated at 20 °C.1. The anodic oxide aluminum films with electrodeposited Ag have an antibacterial activity over 95% against the growth of E. coli, P. aeruginosa, S. faecalis and S. aureus. 2. By using AC electrodeposition, the Ag nanowires can be prepared in pores of the anodized aluminum film, and the diameters of the nanowires are 10 or 25 nm.In this work Ni nanowires embedded in 18cm2 anodic aluminium oxide templates were synthesized by electrodeposition to develop microwave absorbing materials. The complex permittivity and permeability properties of the Ni nanowires composite have been measured in the frequency range of 2–18GHz.

Then, under a certain applied voltage, an insulator oxide barrier layer is formed. In brief, the process involves the migration of oxygen-containing ions (O2 −and OH ) into the metal from the metal-oxide interface, while the metal ions can either form an oxide layer or be released to the electrolyte.The conditions applied during the electrochemical polishing of aluminum were found to be important parameters for the successive formation of nanoporous alumina films. First, a high-purity Al foil was electrochemically polished in an aqueous solution containing C2H5OH and HClO4 at various sets of conditions, such as applied potential (5–35 V), temperature …Anodizing. These carabiners have an anodized aluminium surface that has been dyed; they are made in many colours. Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called anodizing because the part to be treated forms the anode electrode of an ...Taking into account all the test results, it can be concluded that the anodic oxide coating can be considered as an anti-corrosion protection for architectural elements fabricated using EN AW-6063 with working conditions below 60 °C, as the experimental results proved that the durability of such coating is reduced when the temperature of the …Anodic oxidation of valve metals, particularly, aluminum, has attracted considerable attention because of its wide application in various fields oftechnology.
