Y-TiAl intermetallic alloy have a good potential for use as biomaterial, due to its good corrosion resistance. In this paper, two fundamental electrochemical techniques namely electrochemical impedance spectroscopy and potentiodynamic anodic polarization were used to evaluate the corrosion performance of g-TiAl in Ringer's solution. Surface modification treatments were employed with the pur...

Erosion corrosion of an usual carbon steel in a variety of aqueous slurries of 10% Al2O3 powder composed of 0.1M NaOH, concentrated cooling water (synthetic rather than natural), 3% NaCl, and 0.01M HCl was investigated from the electrochemical point of view. The total weight loss, Wt, was experimentally divided into the following three terms: the mechanical loss, Wm, the corrosion loss, Wc, and...

Corrosion of steel reinforcement in concrete is generally considered as an electrochemical process which reduces the service life of a structure exposed to chloride ions attack. Therefore, laboratory experiments were performed in order to ascertain the effectiveness and sustainability of ternary inhibitors (calcium nitrite, ethanolamine and eco-friendly green Bambusa Arundinacea) in protecting ...

To improve the repair effect of electrochemical chloride extraction, a modified electrode configuration is applied in this investigation. In this configuration, two auxiliary electrodes placed in the anodic and cathodic electrolytes were used as the anode and cathode, respectively. Besides this, the steel in the mortar was grounded to protect it from corrosion. By a comparative experiment, the ...

Schiff base (E)-2-methyl-N-(tetrazolo[1,5-a]quinolin4-ylmethylene)aniline (QMA) was synthesized, and its inhibitive effect for mild steel in 1N HCl solution was investigated by weight loss measurement and electrochemical tests. From the weight loss measurements and electrochemical tests, it was observed that the inhibition efficiency increases with the increase in the Schiff base concentration ...

The electrochemical corrosion behavior of NiTi alloy electrodeposited conductive polypyrrole (PPy) coatings doped with small size sulfate (SO42 ), medium size para-toluene sulfonate (pTS ) and large size dodecylbenzene sulfonate (DBS ) counter anions has been studied by electrochemical measurements and surface analysis. It is demonstrated that PPy coatings inhibit the corrosion of NiTi substrat...

Previous studies have demonstrated that the wear-corrosion synergism can be markedly affected by the loading speed. In this study, effects of the loading speed or strain rate on corrosion and corrosive wear of annealed, impact-fractured and slow bending-fractured surface layers of AISI 1045 steel in a 3.5% NaCl solution were investigated using electrochemical, scanning Kelvin probing and electr...

In this paper, the corrosion resistance of laser-welded composite arch wire (CoAW) with Cu interlayer between NiTi shape memory alloy and stainless steel wire in artificial saliva with different concentrations of protein was studied. It was found that protein addition had a significant influence on the corrosion behavior of CoAW. Low concentration of protein caused the corrosion resistance of C...

The electrochemical behavior of mild steel in bicarbonate solution at different dissolved oxygen (DO) concentrations and immersion times has been studied under dynamic conditions using electrochemical techniques. The results show that both DO and immersion times influence the morphology of the corrosion products. In comparative tests, the corrosion rate was systematically found to be lower in s...

vanillin offers interesting possibilities for corrosion inhibition because of its safe use and highsolubility in water. the effect of vanillin on the corrosion inhibition of aisi 304 stainless steel in0.5m h2so4 solution has been studied using potentiodynamic polarization and electrochemicalimpedance spectroscopy (eis). furthermore, this paper demonstrates that the electrochemical noise(en) tec...
