ABSTRACT:
Method for examining the sliding friction between exposed surfaces of different combinations of materials, characterized by the fact that a first test piece of a first type of material and a second test piece of a second type of material are moved against one another over a certain distance and under a certain load while a lubricant is applied between the exposed surfaces, whereby the required energy is measured and this step is subsequently repeated a number of times at various bulk temperatures of the lubricant, following which the measured energy consumption is plotted on a graph as a function of the bulk temperature of the lubricant.
