Use of Electrochemical Tests for Assessment of the Effect of Erosive Particle Size on the Erosion-Corrosion Behaviour of AISI 304L Austenitic Stainless Steel

Microstructure, mechanical and tribological properties of high velocity oxy fuel thermal spray coating: A review

“…The erosion‐corrosion behavior of austenitic stainless steel (AISI 304 L) revealed that the increase in the current density decreased the corrosion resistance. Introduction of big particle led to less polarization resistance [49].…”

An Erosion-Corrosion Investigation of Coated Steel for Applications in the Oil and Gas Field, Based on Bipolar Electrochemistry

“…Erosion-corrosion processes involve complex mechanical and electrochemical mechanisms whose combined action often results in a significant increase in material degradation [1,[16][17][18]. The degradation mechanism is affected by factors controlling both corrosion and erosion.…”

“…Their interaction may result in a synergistic behavior, where erosion may enhance the corrosion rate, or in an antagonistic behavior, where oxidation can slow down the erosion rate [1,14,19,20]. In the classical approach, the synergism is defined as the difference between the total corrosion-wear mass loss and the sum of the corrosion and wear mass losses, measured separately [18]. The interaction between erosion and corrosion has been investigated using various electrochemical and non-electrochemical methods.…”

“…Non-electrochemical sensors based on the electrical resistance technique and acoustic sense technique have been developed to probe the erosion-corrosion behavior, though they have limitations in providing detailed information of the erosion and corrosion processes and their synergistic effects [21]. Electrochemical measurements, such as potentiodynamic polarization, open circuit potential measurements, ellipsometry, electrochemical impedance spectroscopy and electrochemical noise methods, give significant information about erosion-corrosion mechanisms, which greatly affect the electrochemical state of the surfaces [18]. Electrochemical techniques enable us to determine the effect of wear on the active/passive behavior of materials at different potentials and evaluate changes in the kinetics which controls the rate of corrosion [18].…”

Electrochemical devices based on rotating disc or cylinder electrode and slurry jet impingement facility are frequently used [7][8][9][10][11][12][13][14][15].…”
