SUMMARY:MEAM Seminar: "Tribosintering of Metal Oxide Nanocrystal Antiwear Additives: Growth\, Wear\, and Modeling"
DESCRIPTION:Machinery relies on lubrication to regulate the friction and wear at contacting interfaces. As new lubricants become less viscous to comply with environmental and cost-saving standards\, the risk of surface-initiated machine failure grows. We show that metal oxide additives in low-viscosity lubricants will form protective coatings\, or tribofilms\, in situ at contacting interfaces. Compared to state-of-the-art surface coatings and anti-wear additives\, metal oxide coatings have several practical benefits and environmental advantages\, but their formation mechanism is not well-understood. We will first discuss the mechanistic and practical implications of the coatings’ cooperativity of with S- and P-based co-additives\, then the interplay between the coatings’ growth on and their removal from contacting machinery. Finally\, we will discuss data-driven and traditional modeling efforts to develop predictive models for these antiwear coatings.
