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...

Abstract This research aimed to study the induction in-situ heated hybrid friction stir welding (IAFSW) method join AA5052 aluminium alloy with X12Cr13 stainless steel (SS) enhance joint strength. The potency of this on mechanical properties and microstructural characterizations were also investigated. results show that transverse tensile strength gained was 94% base metal is 229.5 MPa. superio...

The corrosion behaviour of aluminium and6063 aluminium alloy was investigated in phosphoric acid of different concentrations at different temperatures. The study was done by electrochemical method, using Tafel polarization and electrochemical impedance spectroscopy (EIS) techniques. The kinetic parameters and thermodynamic parameters were calculated using Arrhenius theory and transition state t...

The paper deals with the optimization of welding parameters of friction stir welding of different Aluminium alloy groups. For this purpose 5 series Aluminium alloy Al 5083 and 6 series Aluminium alloy Al 6062 were taken .Tensile Strength test and micro structure analysis under various rotating speeds and tool profiles is conducted. It is observed that the increase in tool rotation speed and the...

The usage of powder metallurgy aluminium compacts in lieu of ferrous components in automotives helps to lower vehicle weight. The major drawback in the commercially available press sintered aluminium alloy is porosity which is mainly dependent on the powder metallurgical process parameters such as compaction pressure, sintering temperature and cooling rate after sintering. In this paper the eff...

Sixty patients with mallet finger deformity were randomly treated with either a Stack or a custom-made padded aluminium alloy malleable finger splint. Both splints were equally effective in correcting the deformity but the aluminium alloy splint was able to be fitted to a wider variety of finger shapes and sizes and caused significantly fewer skin complications.

The high strength Al-Zn-Mg alloy is widely used for structure components in critical aerospace applications. Small additions of scandium (Sc) often refine cast microstructure and mechanical properties by forming metastable Al3Sc dispersoids. The main role of the Al3Sc dispersoid is to prevent recrystallization during hot deformation and solution treatment. A new technique to apply for surface m...

It is difficult to improve the quality of friction stir welded joints AA5052-H32 material because scarce metrics on its concurrent optimization and prioritization. However, objective this article obtain optimal parametric values identify important parameters using Taguchi-Pareto method during welding process material. Then ranks, delta are determined. The critical identified for tool pin, rotat...
