Cryogenic Tribology of Advanced Materials
|
Abstract:
This talk will begin with an overview of the development of a custom cryostat used to house a unique cryogenic compatible tribometer, as well as the development of several versions of the tribometer itself. The behavior of two classes of materials will be presented along with the general tribological principles uncovered by this research. Specifically, changes in the coefficient of friction of artificial diamond coatings led to a stronger understanding of the influence of surface chemistry on friction and studying the tribology of superconducting materials led to results indicating the lack of influence from electron movement on the coefficient of friction.

Bio:
Dr. Matt Aggleton is currently consulting for Otto Aviation, performing aerodynamic stability calculations for a newly designed airplane. Prior to consulting, he spent two years managing the engineering department at Thermal-Vac Technology where he led the re-invention of the engineering department to provide high level hands-on brazing support for aerospace and medical device customers. Dr. Aggleton taught physics and math at the Art Institute of Orange County before that, presenting the first physics course that AIOC had seen in half a decade. Dr. Aggleton’s graduate research involved using low temperature as a means to probe the basic mechanisms involved in friction. Dr. Aggleton holds a doctorate degree in chemical and materials physics from the University of California, Irvine and a bachelors degree in physics from Rochester Institute of Technology.
