The synthesis of polyaniline- Fe2O3 nanocomposite coating on aluminum Alloy 5052 (AA5052) surface has been investigated by using the galvanostatic method. The anticorrosion performance of polyaniline-Fe2O3 coating was investigated in 3.5% NaCl solution by the open- circuit potential (OCP), Tafel polarization technique and Electrochemical Impedance Spectroscopy (EIS). The corrosion rate of polya...

In this study, the global texture evolution in a 2 mm gauge hot band of continuous casting AA5052 aluminum alloy, annealed at 449 °C for 4 hours, was investigated. Samples were deformed to three different strain values under a near equi-biaxial stretching condition. Their textures were. The major and minor strains of these samples were measured using an automatic strain analysis system. The tex...

Nowadays, 80–90% of the components airplanes are composed aluminum alloys. Another material with a high level corrosion resistance and is utilized in aircraft AA5052. When exposed to natural environment, AA5052 forms an oxide layer that shields alloy from corrosion. However, this eroded corrodes more quickly harsh weather conditions where aeroplane operates. On substrate, multilayered nanostruc...

Aluminum alloys have a high strength-to-weight ratio and proper anti-corrosion properties that are used in the automotive, shipbuilding and aerospace industries. The major problem with forming aluminum sheets is the low formability of aluminum sheets at room temperature. Therefore, in the present study, warm deep drawing (WDD) of AA5052-O aluminum alloy sheets with a thickness of 1mm was invest...

The welding of non-heat treatable aluminum alloy AA5052-H34 was performed using pressure-controlled joule heat forge method. dislocation density the work hardened decreases at high temperatures, and it is difficult to suppress affected softening zone during welding. In addition, since alloys have a thermal conductivity, transfer likely occur, control temperature. Therefore, in this study, by op...

This study evaluated the performance of aluminum-copper alloy filtration, without the original aluminum filter, for dental radiography in terms of x-ray energy spectrum, air kerma rate and image quality. Comparisons of various thicknesses of aluminum-copper alloy in three different percentages were made with aluminum filtration. Tests were conducted on an intra-oral dental x-ray machine and wer...
