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...

Platinum stability: Dissolution of Pt, which is one major degradation mechanism in, for example, hydrogen/air fuel cells, was monitored under potentiodynamic and potentiostatic conditions. The highly sensitive and time-resolving dissolution monitoring enables the distinction between anodic and cathodic dissolution processes during potential transient and chronoamperometric experiments, and the ...

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...

The aims of this study were to investigate the effects of Zr addition and potentiodynamic polarization on the microstructure and corrosion resistance of Ti–22Nb and Ti–22Nb–6Zr alloy samples. The corrosion tests were carried out in 0.9% NaCl at 37 8C and neutral pH value, utilizing the OCP, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS) techniques.The results of ...

In the present investigation, a detailed mechanical and electrochemical properties of multiple-layer laser clad 316L stainless steel (from the powders produced by gas atomized route) has been carried out. Multiple-layer laser cladding of 316 L stainless steel has been conducted using a diode laser. The mechanical property (microhardness) of the fabricated product has been evaluated using a micr...

We have investigated electrical properties of symmetric alkanethiolate bilayer junctions formed by contacting two hanging mercury drop electrodes each coated initially with a single alkanethiolate monolayer. Using potentiodynamic, current transient and ac impedance methods, we have shown that the initial, largely all-trans structure of the bilayers becomes disordered with time as a result of th...

the effect of chloride ions concentration on the electrochemical behavior of aisi 410 stainless steel in thesimulated concrete pore (0.1 m naoh + 0.1 m koh) solution was investigated by various electrochemicalmethods such as potentiodynamic polarization, mott–schottky analysis and electrochemical impedancespectroscopy (eis). potentiodynamic polarization curves revealed that increasing chloride ...
