An analytical ultra-high vacuum tribometer: application to tribochemistry in metal rolling
The demand for improvements in surface quality and increased productivity in industrial cold metal rolling requires a good understanding of lubrication mechanisms. The limitations are due to boundary friction, controlled by the physico-chemistry of lubricant additives. The phenomena are complex and require a simplified approach. Consequently, a new method was developed by using an UHV tribometer associated with surface analytical tools to simulate the molecule chemical reactivity toward surfaces.
