An Overview of Major Experimental Methods and Apparatus for Measuring and Investigating Erosion-Corrosion of Ferrous-Based Steels

Abstract

This paper firstly provides an overview of major efforts made over the past several decades on developing the test apparatus for the study of erosion-corrosion of ferrous-based steels. The merits and the application range of the set-ups, i.e., rotating disc/cylinder electrode system, slurry jet impingement rig, and test flow loop, are introduced. Secondly, the advantages and limitations of both non-electrochemical and electrochemical methods used for the measurement of erosion-corrosion are presented. Thereafter, the interaction between erosion and corrosion using a cyclic erosion-corrosion method was introduced. The synergy between erosion and corrosion for the steels under the passive state were analyzed on the basis of the breakdown and restoration of the passive film. In addition, the difference between the obtained erosion-enhanced corrosion and the corrosion-enhanced erosion using different experimental methods for steels under active corrosion was discussed. Finally, the interaction between the localized corrosion and erosion was studied through the dynamic change of the local current distribution revealed by the wire beam electrode.

Erosion–Corrosion of AISI 304L Stainless Steel Affected by Industrial Copper Tailings

“…Under certain circumstances, such as pH variations and the presence of aggressive ions in solution such as chlorides, a local corrosion potential on small areas can evolve to more positive values, close enough to pitting potential, generating a detrimental condition of autocatalytic pitting. In this form of corrosion, while passivity breakdown occurs on small areas of the metal surface, the rest remains passive [9,14,16,30]. to pitting potential, generating a detrimental condition of autocatalytic pitting.…”

“…to pitting potential, generating a detrimental condition of autocatalytic pitting. In this form of corrosion, while passivity breakdown occurs on small areas of the metal surface, the rest remains passive [9,14,16,30]. The deconstruction of polarization curves that was performed using the superposition model in the context of the mixed potential theory (Equations (2) and ( 3)) [29] is shown in Figure 7.…”

“…In the presence of slurries, pitting corrosion can be increased as a result of synergistic interaction with solid particles that impinge upon the metal surface. The corrosion rate and passive film breakdown have been extensively studied in austenitic stainless steel [5,[8][9][10][11][12], covering situations when this material is also subjected to mechanical damage from solid particles [13][14][15][16][17][18][19], which is described as an erosion-corrosion phenomenon [20].…”

The Effect of Sandblasting on Properties and Structures of the DC03/1.0347, DC04/1.0338, DC05/1.0312, and DD14/1.0389 Steels for Deep Drawing

“…The erosion phenomenon has a significant influence on many metallic materials used in many industrial sectors [1,2]. Sandblasting is the operation of applying a stream of abrasive material under high pressure against a surface to clean it or change its geometry or properties.…”

Corrosion Prediction of Weathered Galvanised Structures Using Machine Learning Techniques

“…The character of the attack and the corrosion rate are consequences of the system formed by metallic materials, atmospheric environment, technical parameters, and operating conditions [ 10 ]. Corrective factors are introduced in the design phases to guarantee the structure’s integrity during its useful life [ 11 ]. However, the difficulty of quantifying the material loss causes unnecessary over-dimensioning, leading to superfluous costs and resources consumption [ 12 ].…”
