Electrochemical Behavior of Titanium Alloys Using Potentiodynamic Polarization

ECS Transactions, 2021
Titanium is for aerospace production is of 80%. In an aircraft structure, 15% of the weight is titanium. The principal reasons to use titanium alloys are the save of weight, increase performance temperatures ratio and corrosion resistance. To analysed corrosion behavior of Ti alloys, polarization potentiodynamic cyclic was employed.

Potentiodynamic polarization behavior of YBa2Cu3O7−x superconductor

Materials Letters, 1987
Abstract Aqueous corrosion behavior of YBa 2 Cu 3 O 7− x superconductor was studied in 1 M H 2 SO 4 and 0.1 N NaCl solutions by the potentiodynamic polarization technique. The corrosion rate was found to be higher in 1 M H 2 SO 4 than in 0.1 N NaCl solutions. In comparison to pure Cu, YBa 2 Cu 3 O 7− x is more stable in these solutions.

Unique Interpretations of Potentiodynamic Polarization Technique

CORROSION 1998, 1998
Abstract Development of the cyclic potentiodynamic polarization (CPP) technique and interpretation of the resulting curves was based primarily upon the stainless steel-aqueous chloride system. This paper presents and interprets CPP curves for this and other alloy-environment systems.

Corrosion testing by potentiodynamic polarization in various electrolytes

Dental Materials, 1992
The effect of different electrolytes on the results from potentiodynamic polarization corrosion testing was studied for nine different dental alloys. In general, the difference in the results was greater between certain alloys using the same electrolyte than between the electrolytes with the same alloy.

Improved Data Recording for Automatic Potentiodynamic Polarization Measurements

Corrosion, 1968
Improvements in instrumentation for automatically plotting potentiodynamic polarization curves by using a scanning potentiostat, a logarithmic converter, and an X-Y recorder are described. An accessory circuit permits uninterrupted recording of polarization currents from 10−2 to 107 μa and virtually eliminates operator attention.

Tutorial on Cyclic Potentiodynamic Polarization Technique

CORROSION 1998, 1998
Abstract The cyclic potentiodynamic polarization technique provides a reasonable, rapid method for qualitatively predicting the propensity of an alloy to suffer localized corrosion in the form of pitting and crevice corrosion. Better and more accurate techniques are available for estimating general corrosion rates.

Use of potentiodynamic polarization technique for corrosion testing of dental alloys

European Journal of Oral Sciences, 1991
Abstract— The number and in particular the diversity in types and composition of alloys used in dentistry are increasing, thus enhancing the need for predictive corrosion testing. No corrosion test is generally accepted as being both applicable to and relevant for all dental alloys.

Potentiodynamic polarization study of the corrosion behavior of palladium-silver dental alloys

The Journal of Prosthetic Dentistry, 2018
Although palladium-silver alloys have been marketed for over 3 decades for metal-ceramic restorations, understanding of the corrosion behavior of current alloys is incomplete; this understanding is critical for evaluating biocompatibility and clinical performance.The purpose of this in vitro study was to characterize the corrosion behavior of 3 ...
