Course content

This project strives to solve an application-driven problem of limited durability of automotive electrical connectors due to fretting-corrosion.

Fretting-corrosion results from vibrations, variable humidity and temperature; it increases electrical contact resistance as corrosion products change the nature of the metallic interface.

Improvement of the connector performance will be achieved by introducing tailored surface texturing and developing a fundamental understanding of the oxidation process at the functionalised interface. A pilot study showed a non-linear correlation between surface roughness and electrical contact durability.

This project has a strong industrial support from Mercedes-Benz, PCT Automotive and DuPont Teijin Films. Cross-faculty collaboration with School of Electrical and Electronic Engineering will be sought.
