Studies on Surface Processes during Friction and Wear,
Abstract
In the previous contract period, experimental as well as theoretical research has been carried out. The former has concentrated on the development of a novel testing apparatus which promises to reveal hitherto inaccessible details on the surface condition of materials during sliding. It employs simultaneous measurements of the coefficient of friction and the electrical contact resistance, using a soft set-up and following the momentary variations. This research has not yet yielded reportable results but progress is most encouraging. Theoretical work has been devoted to theory of plastic deformation. Of by far the greater interest in connection with the present contract theme, namely friction and wear and surface processes governing these, has been the research embodied in the two extensive papers which are appended herewith. As is seen from these, it has been possible to derive rather simple analytical, closed equations for the evaluation of the momentary temperature at contact spots during sliding. This theory has been extended to the case of concurrent friction and Joule heating, as presented in this paper, which has been submitted to the WEAR OF MATERIALS - 1985 conference. This document concentrates on de-mystifying flash temperatures. Additional keyword: Computations.
