Copper-bearing intrauterine devices(Cu-IUDs) are being increasingly used all over the world. However, the dissolution of copper in the presence of proteins is not well characterized. Here, with open circuit potential, electrochemical impedance spectroscopy measurements and potentiodynamic polarization test, the corrosion behavior of copper samples in different single-protein simulated uterine s...

Titanium alloys are used in different industries such as biomedical, aerospace, aeronautic, chemical, and naval. Those have high requirements with few damage tolerances. The aim of this work was to study the corrosion behavior titanium anodizing non-anodizing alkaline (KOH NaOH) solutions, exposed 3.5%wt. NaCl 3.5% wt. H 2 SO 4 solutions at room temperature using cyclic potentiodynamic polariza...

Nitrogen doped tetrahedral amorphous carbon (ta-C:N) thin films were grown on p-Si(1 1 1) substrates using filtered cathodic vacuum arc (FCVA) deposition by varying nitrogen flow rate. The effect of nitrogen flow rate on the corrosion performance of the films was investigated through potentiodynamic polarization and immersion tests in 0.6 M NaCl solutions. The polarization results showed that t...

The effect of marine algae Sargassum wightii extract on corrosion inhibition of brass in phosphoric acid was investigated by weight-loss method, potentiodynamic polarization and electrochemical impedance spectroscopy studies. The inhibition efficiency is found to increase with increasing concentration of extract and decreases with rise in temperature. The inhibitive effect could be attributed t...

The inhibitive action of alkali extract human hair extract (Bio waste) against the corrosion of mild steel (98.58%) in solutions of nitric acid has been studied using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). At inhibitor concentration range (0.004 % v/ v to 0.1% v/v) in 0.3 M HNO3acid, the results showed that these compounds suppressed both cathodic and ano...

The corrosion inhibition of AISI309 austenitic stainless steel by 2,2'-Bipyridyl in 0.5M H 2 SO 4 at 298K was studied using the mass loss’ method, the potentiodynamic polarization (Tafel), the linear polarization (LRP) and the electrochemical impedance spectroscopy (EIS). The results showed a mixed inhibition mode and an increase in the charge transfer resistance, due to inhibitor molecules’ ad...
