Important features of elevated temperature tribological degradation sliding wear

3 Important features of elevated temperature tribological degradation sliding wear 

Interest in elevated temperature sliding wear has been generated in recent years. A compilation of the relevant literature is presented in ref. [20]. On the basis of the reported literature, the important features of elevated temperature sliding wear are described below. 

4 (a) Variation of friction coefficient as a function of sliding distance at various temperatures for PM 1000 alloy against self-mating surface [21) (b) and (c) variation of friction coefficient as a function of temperature [21, 23-25) (d) influence of test temperature on the wear rate of Nimonic 80A and MA 956. 

The effect of sliding velocity on friction coefficient and wear rate 

(b) Variation of thickness ioss as a function of siiding distance for MA 253 and PM 1000 aiioys at different test temperatures [21,23].
