The corrosion behavior of TiZrHfBeCu(Ni) high-entropy bulk metallic glasses (HE-BMGs) has been investigated. The TiZrHfBeCu(Ni) HE-BMGs exhibited high corrosion resistance in 3.5 wt. % NaCl solution because of accumulation of ZrO2 and TiO2 in the passive
NaCl is a neutral compound as it has a pH value of 7. It is neither acidic nor basic in nature. NaCl is neutral as it is formed by the neutralization reaction of HCl (strong acid) and NaOH (strong base). The strong acid and strong base in the aqueous solution neutralize each other ...
Because Raman scattering intensity of dispersed solute molecules is inherently weaker than that of crystals composed of the same compound, a high concentration of Na2CO3was necessary to generate sufficiently strong Raman signals. We therefore set the concentration of Na2CO3at 2 M, which was recommend...
When the bias voltage is low, the energy of sputtering ions is weak, and the thermal effect that is created by the deposition process is minimal as well. In addition, the film is deposited at a fast pace, and the surface diffusion is not adequate to relieve the rapid buildup of local ...

Due to the weak reaction between CO2 and water, the concentrations of HCO3− and CO32− ions are low. In this work, no HCO3− and CO32− ions can be found in the measured Raman spectra of H2O-CO2 or H2O-NaCl-CO2 systems. This is also in accordance with Davis and Oliver’s ...
The corrosion behavior of a novel Mg0.5Zn0.2Ge alloy in as-cast and extruded conditions is investigated in 0.9 wt.% NaCl solution. Scanning kelvin probe force microscopy measurements and local electrolyte drop corrosion tests demonstrated that the matrix dissolved preferentially in corrosive solution...
Rare earth (RE) containing Mg alloys exhibiting superior high temperature properties are considered as potential candidates for automobile applications[1]. However, the corrosion behavior of Mg-RE alloys is not well understood. It is well documented that the RE additions improve the corrosion resistanc...
The constant ionic medium method, which consists of adding in the solution a supporting electrolyte at concentration higher with respect the components, for different order of magnitude was used for the investigations. In this order, it is possible to assume that the activity coefficient of the com...
When solutes such as NaCl, MgCl2 and CaCl2 (or any combination of them) are present, the solubility of CO2 in brine is greatly impacted. In reality, because of the enhanced salting-out effect, the solubility reduces as the salinity rises (the salting-out effect is discussed in detail in ...
