| Abstract Scope |
Tribocorrosion has gained renewed attention due to increased demand for wear- and corrosion-resistant materials in industries such as biomedical implants, nuclear power, manufacturing, batteries, and marine applications. In the U.S., wear and corrosion cost nearly USD 300 billion annually. Passive metals like aluminum alloys are particularly vulnerable to tribocorrosion due to wear-accelerated corrosion from passive film removal. Designing aluminum alloys with improved tribocorrosion performance is crucial. This talk reviews five decades of research on aluminum alloy tribocorrosion, including those from our own work. It focuses on: (1) the effects of alloying and grain size on wear, corrosion, and tribocorrosion mechanisms; and (2) alloy design strategies to enhance tribocorrosion resistance. Finally, this talk addresses some of the current challenges faced and outlines a few future research directions in the field of tribocorrosion of aluminum alloys. |
