Friction, Lubrication and Wear (Tribology)
Friction and associated wear between sliding and/or rotating components is a major factor in high energy cost and fluid contamination. Significant reductions in these effects can be achieved by optimising the lubrication film between the components. Our knowledge of fluid dynamic and engineering are used to improve and optimise the tribological behaviour of lubricated systems which together with our experience of fluid-material compatibility are employed to improving the operating lifetime and effectiveness of many engineering processes.
