Lubricated shafts, bearings and gears only run 'like clockwork' when the components slide on a perfect lubricating film, generating as little friction, wear and energy loss as possible. To achieve this, engineers need to know the behavior of the lubricant film in the so-called tribo-contact, which is difficult to measure experimentally. In order to ascertain such behavior, the Fraunhofer IWM, MicroTribology Center μTC makes lubricant properties calculable using atomistic methods and has recently published exciting findings on one of the central parameters, the pressure dependence of lubricant viscosity, in the scientific journal Physical Review Letters.more info
