plasma electrolytic oxidation (peo) was performed on a 1010 aluminum alloy. to achieve thenanocomposite structure, si3n4 nanoparticles were added into the electrolyte. in an alkaline aqueoussuspension (silicate-based), the effect of adding niso4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of peo coatings was investigated using scanningelectron microscopy (...
The effect of anodic oxidation of a NiTi shape memory alloy in sulfuric acid electrolyte on its surface characteristics was studied. Surface roughness was measured by roughness tester. Surface morphology was studied using optical microscopy (OM) and scanning electron microscopy (SEM). Corrosion behavior was specified by recording Potentiodynamic polarization cur...
The effect of recasting, up to two times, Ni-Cr (DUCINOX) prosthetic alloy on its corrosion properties was carried out. The corrosion measurements were done in deoxygenated Fusayama Meyer artificial saliva solution at temperature of 37°C. In the study following electrochemical methods were used: measurement of free corrosion potential Ecor in open circuit, measurement of polarization resistance...
titania nanotubes (tnt) prepared by anodization of ti foils were used for water splitting in a standalone cell. the concentration polarization between the anode side (1m naoh) and cathode side (0.5 m h2so4) ensured that the water splitting reaction could take place with no external bias and separate h2 and o2 evolution could be achieved. the destruction of tnt structures under 365 nm uv irradia...
This paper investigates the application of an electrochemical technique for the removal of a common herbicide, bentazone, from water streams using a carbon-based electrode. Activated carbon cloth with high surface area and narrow micropores was used as electrode. For a better understanding of the process, adsorption was investigated under both open circuit and controlled polarization conditions...
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...
