Contact mechanics of engineered surfaces

Cel

Lubricious coatings, such as diamond-like carbon, can dramatically improve the tribological performance of engineering components, where tribology is the science of friction, wear, and lubrication of solids during their relative motion. Possible improvements include increased component durability as well as increased efficiency due to the reduction in friction. The effective use of such coatings is hindered however by the absence of accurate models to predict the tribological behaviour of coated bodies without recourse to time-consuming experimental investigations.
The main objective of this project is to develop and validate models for the tribological behaviour of components with lubricious surface coatings. Initially simple models will be developed considering sliding contact between a coated surface and a single asperity. These models will subsequently be extended using topographical and mechanical information yielded by nanometre scale studies of real coated bodies. Predictions from the extended models will be compared to experimental results for coated and uncoated components in a number of different tribological environments. These comparisons will serve as a first-level validation of the models.
The models will then be used to make recommendations regarding the roughness, thickness and mechanical properties of coatings for optimised tribological performance under a range of different conditions. Components with these optimised surface treatments will be fabricated and tested. Final validation of the models will be sought by comparing the tribological behaviour (wear rate and friction) of components with these optimised coatings to the behaviour of components with sub-optimal coatings.
This project seeks to deliver new insights into the microgeometry, structure and mechanical properties of thin lubricious coatings. Contact mechanics models for coated components will be developed based on these insights. The information gleaned by this investigation will lead to more effective employment of lubricious surface coatings and, therefore, more widespread enjoyment of the benefits that such coatings can provide.
