Combinational analysis of multi-data obtained in a repeated sliding system

The author proposed a new analysis method to conjecture friction and wear mechanisms for the repeated sliding test performed with a pin-on-disk apparatus. Two kinds of data, friction force and pin displacement perpendicular to the sliding surface, were analyzed to obtain a frequency distribution chart of the combinations of these two kinds of data. The devised analysis method was applied to data obtained in adhesive and abrasive wear systems to verify its function. The method successfully differentiated these two sliding systems, and detailed time dependent changes of each system were described.
