Electrochemical Synthesis of Polypyrrole on Aluminium in Different Anions and Corrosion Protection of Aluminium1
In this study, polypyrrole was deposited on the aluminium in different anions (C N Cr DBS–). The contribution of anions to formation of polypyrrole film was investigated by using cyclic voltammetry (CV) technique. The effect of polypyrrole film on the corrosion of aluminium was searched in 0.1 M HCI solution by using potentiostatic method. For this purpose, polarization curves were obtained, co...
متن کاملSTUDY ON CORROSION PROPERTIES OF PLASMA NITRIDED PURE ALUMINIUM
Abstract: In this research plasma nitriding of pure aluminium and effect of iron elemental alloy on the formation and growth of aluminium nitride was investigated. Also corrosion properties of formed AlN were investigated. After preparation, the samples were plasma nitrided at 550oC, for 6, 9 and 12 h and a gas mixture of 25%H2-75%N2. The microstructure and phases analysis were investigated usi...
متن کاملElectrochemical evaluation of corrosion protection performance of epoxy/polyaniline-imidazole modified ZnO nanocomposite coating on mild steel
In this research, ZnO nanoparticles modified with imidazole in O-xylene solution and characterized with Fourier transform infrared FTIR spectroscopy. Then, polyaniline-ZnO unmodified and imidazole modified nanocomposites were synthesized via in-situ emulsion polymerization method. The synthesized nanocomposites were characterized by FTIR and scanning electron microscopy SEM. The anti-corrosion ...
متن کاملElectrochemical Synthesis of Polyaniline Nanoparticles and Nanofibers
The electrochemical deposition of polyaniline nanofibers and nanoparticles have been investigated on gold electrodes by cyclic voltammetry and their morphology by high resolution scanning electron microscopy and atomic force microscopy. The type and dimensions of the nanostructures obtained depend on deposition conditions such as monomer concentration, scan rate and electrical potential. We hav...
متن کاملElectrochemical Evaluation of Polyvinyl Butyral Coating Containing Polypyrrole/ZnO Nanocomposite for Corrosion protection of Al Alloy
In this work, polypyrrole/ZnO nanocomposite (PPy/ZnO NC) was produced through synthesis of polypyrrole polymer in the presence of ZnO nanoparticles. The corrosion behavior of polyvinyl butyral coatings without and with different weight percentages of nanocomposite on the surface of 7075 Al alloy was investigated in 3.5% NaCl solution at different immersion times using electrochemical impedance ...
