“…In terms of microstructure engineering, those that favor electrochemically benign strengthening mechanisms are also worth exploring, which will likely strengthen the material and increase the hardness without compromising the corrosion resistance. For example, recently, Jia et al [168] showed that deep cryogenic treatment (DCT) provides a driving force for nucleation and growth during the re-aging treatment of the AA2024 alloy. The combined aging and DCT treatment significantly improve the wear resistance of AA2024 without affecting the corrosion resistance, which is likely to enhance the overall tribocorrosion resistance.…”

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.
