Correlations between the Volta potential and filiform corrosion on painted AA2024 aluminum alloy
Surface and Interface Analysis, 2009Abstract The susceptibility to filiform corrosion of painted AA2024 alloy has been widely demonstrated, but an analytical method to determine the filiform corrosion resistance is still under investigation. This work aims at analyzing the possible correlations between the chemical and electrochemical properties of coated AA2024 samples

Relative Volta Potentials of Intermetallics in AZ91-RE Mg Alloy After Solution and Aging Treatment
Journal of Nanoscience and Nanotechnology, 2019AZ91 alloy with 1.0 wt.% (La, Ce) mischmetal (MM) addition was solution treated at 593 K for 4 h, 653 K for 2 h and 693 K for 8 h (T4), which was subsequently aged at 493 K for 5 h, 8 h and 11 h, respectively. Solid solution and aging treatment mainly led to the change of number of β-Mg17Al12 phases and the size of mischmetal (MM) intermetallics.

Fresenius' Journal of Analytical Chemistry, 2000
Properties of the new polyaniline containing primer CORRPASSIV sealed with two different top coats are characterised and compared with top coated samples using no or a conventional zinc-rich primer. Measurements were made using scanning Kelvin-probe (SKP), electrochemical impedance spectroscopy (EIS), voltammetry and analysis of iron and zinc content ...

Volta Potentials of the Copper-Nickel Alloys and Several Metals in Air
Journal of Applied Physics, 1951Volta potentials of various metals approximately parallel the emf series. Metals abraded wet are more noble than when abraded dry, the transition metals changing an average of 0.28 volt compared with 0.07 volt for the nontransition metals. This owes possibly to the greater tendency of the transition metals to chemisorb oxygen, especially in the ...

Galvani and Volta Potentials at the Interface Separating Immiscible Electrolyte Solutions
1987Recent progress and main problems of the study of electrochemical equilibrium properties are reviewed for interfaces between two immiscible liquid electrolyte solutions. The discussed properties are mainly described in terms of the Galvani, Volta, zero charge, and surface (dipolar) potentials at the liquid-liquid interfaces and free liquid surfaces ...

The investigation of corrosion of metals and semiconductors by volta potential measurements
Electrochimica Acta, 1962Abstract The interaction of iron, germanium and silicon with oxygen and water vapour was investigated by means of measurements of the chemisorption kinetics and of Volta-potentials. The oxide layer formed on the surface of Fe, Ge and Si by Adsorption of dry oxygen loses its protective properties in the presence of water vapour, so that after the ...

Biomaterials Advances
The Ti6Al4V (TC4) alloy, a prevalent biomedical material in orthopedics, still faces limitation of the insufficient osseointegration. To improve the bioactivity of TC4, introducing the electric environment onto the TC4 surface may be an effective way in the view of the necessity of endogenous electric microenvironment in bone regeneration.

Solvent effects on the volta potential difference at the uncharged metal-solvent interface
Electrochimica Acta, 1989Abstract A two parameter approach to the Volta potential difference at the potential of zero charge for interfaces between various solvents and Hg or Bi is proposed with donor and acceptor numbers of solvents as a measure of metal-solvent and solvent-solvent interactions, respectively.
