چکیده انگلیسی
The present research was carried out to study the combined aspects of impact and sliding failure mechanisms of high chromium sintered steel at different contact temperatures. The tribological behavior (mainly mass loss) was investigated both under reciprocating motion and with a dynamic impact-sliding loading. In case of reciprocating motion, the measured friction coefficient decreases as the contact temperature increases. The presence of oxides seems to be the key factor of this evolution. When for the combined impact with sliding, wear rate and damage mechanisms vary strongly with temperatures. Scanning electron microscopy observations coupled with EDX analysis were performed inside and outside of the wear track in order to understand the surface accommodation with temperatures.
