“…Instead, a network of conspicuous grooves developed on alloy A20 with ~100 nm in depth. Corrosion mechanisms of Al has been reviewed from the perspectives of acid-base interactions [94], chloride ion interactions with surface oxide film [95], critical steps involved in localized corrosion and stressed corrosion [96], and the effects of corrosion inhibitors [97], etc. Specifically, the review by Olugbade [98] discusses the effects of plastic deformation, including ultrasonic shot peening, equal-channel angular processing, constrained groove pressing, etc., and addresses the impacts of deformation on corrosion, which shares some similarity with tribocorrosion for the wear-induced gradient subsurface microstructure [99].…”

Tribocorrosion, a research field that has been evolving for decades, has gained renewed attention in recent years, driven by increased demand for wear- and corrosion-resistant materials from biomedical implants, nuclear power generation, advanced manufacturing, batteries, marine and offshore industries, etc. In the United States, wear and corrosion are estimated to cost nearly USD 300 billion per year. Among various important structural materials, passive metals such as aluminum alloys are most vulnerable to tribocorrosion due to the wear-accelerated corrosion as a result of passive film removal. Thus, designing aluminum alloys with better tribocorrosion performance is of both scientific and practical importance. This article reviews five decades of research on the tribocorrosion of aluminum alloys, from experimental to computational studies. Special focus is placed on two aspects: (1) The effects of alloying and grain size on the fundamental wear, corrosion, and tribocorrosion mechanisms; and (2) Alloy design strategies to improve the tribocorrosion resistance of aluminum alloys. Finally, the paper sheds light on the current challenges faced and outlines a few future research directions in the field of tribocorrosion of aluminum alloys.

“…In order to inhibit localised corrosion, corrosion inhibitors should have the capacity to interact over various lengths and time scales to match those time-dependent processes occurring on alloy surfaces. Environmentally friendly rare earth (RE) compounds have demonstrated complex multiscale interactions when inhibiting corrosion reactions on aluminium alloys, for instance, AA2024-T3 [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

“…Extensive studies have been carried out over previous years on the corrosion inhibition of AA2024-T3 by RE inhibitors [8][9][10][11][12][13][14][15][16][17][18][19][20] using a range of electrochemical techniques including standard electrochemical techniques, volta potential methods (e.g., scanning Kelvin probe (SKP)), scanning vibrating electrode technique (SVET), scanning electrochemical microscopy (SECM) and electrochemically integrated multi-electrode arrays (also known as wire beam electrode (WBE)) under different environmental conditions. Many of the past studies have examined corrosion in the presence of the inhibitors under electrochemical polarisation conditions, not under open circuit potential (OCP) corrosion conditions.…”

This work demonstrates an approach towards the understanding of multi-scale and open-circuit localised electrochemical processes of AA2024-T3 in the presence and absence of an environmentally friendly rare-earth inhibitor; cerium diphenyl phosphate (Ce(dpp)3). At high temporal resolution, a wire bean electrode (WBE) made from 100 identical AA2024-T3 wires revealed sudden increases in galvanic anodic and cathodic activities immediately after dosing of 50 and 100 ppm of the inhibitor and an overall suppression of macro-scale activities by increasing the inhibitor concentration to 200 ppm, suggesting it as a fast-screening tool for inhibitors and measuring inhibition efficiency. At high spatial resolutions, scanning probe electrochemical techniques confirmed local activation of corroding microstructures on individual AA2024-T3 wires similarly by dosing the inhibitor up to 100 ppm. In agreement with WBE findings, the effective shutdown of both anodic and cathodic activities occurred after increasing the inhibitor concentration to 200 ppm confirming the optimal concentration of the Ce(dpp)3 and the mixed mode inhibition mechanism of this selected inhibitor on AA2024-T3.

The rising cases of corrosion problems in pipelines, refineries, water treatment and petrochemical plants, as well as in power generation plants in recent time have been attributed to industrialization. The longevity and dependability of essential assets must be ensured through effective corrosion management. The various techniques applied for corrosion protection are discussed in this review. But in recent years, the development of response surface methods (RSM) and artificial neural networks (ANN) has shown exciting prospects to transform the corrosion monitoring process. This review paper gives a thorough overview of corrosion optimisation strategies. The role of ANN and RSM in predicting corrosion using various parameters is discussed. By providing insights into the current state of research on ANN, this paper aims to promote a deeper understanding. The review emphasises how crucial it is to adequately manage corrosion if essential assets are to last a long time and function consistently.
