The corrosion inhibitive action of flower extracts of Clitoria ternata flower on mild steel corrosion in 0.5 M H2SO4 solution was studied using weight loss method, potentiodynamic polarization and EIS measurements. The results obtained indicate that the extracts functioned as good inhibitors in 0.5 M H2SO4 solution. Inhibition efficiency was found to increase with extract concentration. The ads...

A practical anodic and cathodic curve intersection model, which consisted of an apparent anodic curve and an imaginary cathodic line, was proposed to explain multiple corrosion potentials occurred in potentiodynamic polarization curves of Fe-based glassy alloys in alkaline solution. The apparent anodic curve was selected from the measured anodic curves. The imaginary cathodic line was obtained ...

Electrochemical synthesis of poly ortho toludine (POTD) was achieved on Teflon coated cylindrical stainless steel electrodes with base diameter 2mm . Aniline in 2-propyl pentatonic acid solution was polymerized on the surface of stainless steel using cyclic voltametry technique. Adherent and red polymer films were obtained on the electrodes.. The corrosion inhibitive performance of POTD+2PPA , ...

Corrosion resistance of iron can be drastically improved by addition of passivating alloying elements. A supersaturated solid solution of Fe-25at%Sn was produced by mechanical alloying of commercially pure iron and tin powders for 24 hours using a planetary ball mill. Electrochemical measurements were performed on cold compacted unsintered specimens.. XRD investigation on produced alloy showed ...

In this study, Ni–P–Fe2O3 composite was deposited on AISI 4140 steel using different concentrations of Fe2O3 ranging from 0.1 to 0.5 gr/lit in an electroless bath. The phase analysis and surface morphology the samples were characterized X-ray diffraction FESEM. corrosion behavior coated investigated a 3.5 wt. % NaCl solution through potentiodynamic polarization. results test show that adding in...

Silicon dioxide (SiO2) thin films are most commonly used insulating films in the fabrication of silicon-based integrated circuits (ICs) and microelectromechanical systems (MEMS). Several techniques with different processing environments have been investigated to deposit silicon dioxide films at temperatures down to room temperature. Anodic oxidation of silicon is one of the low temperature proc...

Nanocomposite coatings of TiN/a-C were prepared on tool steel substrates using a multitarget reactive DC magnetron sputtering process at various TiN layer thicknesses (0.6–2.8 nm). The a-C layer thickness was approximately 0.45 nm. Structural characterisation of the coatings was done by X-ray diffraction (XRD). Incorporation of an a-C phase in TiN matrix reduced crystallite size of the coatings...

The effect of vanillin on the corrosion behavior of AA6061 Al alloy in 3.5% NaCl solution wasinvestigated using potentiodynamic polarization and electrochemical noise (EN) techniques. Vanillinoffers interesting possibilities for corrosion inhibition due to its nontoxicity and high solubility inaqueous media. The best inhibition effect at 200 ppm vanillin was a marked characteristic of theinhibi...
