Friction and wear behaviour of metal oxide coatings subject to environmental variations

Metallic materials have been used in various applications such as gas sensors, space lubrication, and power transmission. Under different environmental conditions, materials can have vastly different friction properties. Understanding the wear and friction properties of materials is imperative for determining suitable materials for different applications, although oftentimes poses a challenge. Recently, the Colas Group developed a method to measure wear and friction of bulk metallic glasses, a proposed alternative for traditional metals, under different humidity levels with high levels of reproducibility. The objective of this research is to study the fundamental mechanisms of the environmental effects on friction and wear. Different metal oxide coatings will be deposited and tested under varying conditions to investigate the impact of the environment for different coating chemistries. By understanding the fundamental mechanisms in different environments we can develop and identify materials that are better suited for use in their respective environments.
