Simulation of Friction Composite Behavior Using Heat Treatment

Abstract

One of the factors influencing performance of friction composites is stability (optimal condition) of surface at high temperatures. When measuring coefficient of kinetic friction and volume wear rate, preheating of the cast iron disc is used to simulate behaviour in real conditions. Using this method the comparison of different friction composites can be carried out. The heat treatment of selected samples in inert atmosphere was applied to obtain information about the bulk material and surface changes at gradually increased temperature. We have observed changes in components morphology and phase composition of bulk material and compared it with structure of surface after friction test. We have focused on characterization of friction modifiers, fibrous fillers and resin binder as well.
