Abstract
Sintered iron-based friction materials are expected to per form reliably up to the temperature of 1000oC or even more without substantial or sudden deterioration of frictional properties. One of the main requirements is, therefore, thermal stability, which means that the values of friction coefficient and wear rate do not appreciably change up to the specified maximum temperature [1, 2]. The present state of the theory of friction of metals does not quite exactly explain conditions which ensure thermal stability or, on the other hand, causes for thermal instability of many friction materials. Contemporary theories and known laws governing metallic friction, worked out mainly by Bowden [3], Goodzeit [4], Coffin [5] and Semenov [6], make it possible to select materials with very little wear and suitable coefficient of friction when cold, yet they fail to explain changes in the behavior of friction materials at high temperatures.
