Abstract

Wear diagrams, which are the three dimensional representations of the dependence of the wear rate on the applied pressure and the sliding speed, were constructed with the pin on ring type wear test results using 52100 wear couples. The pressure and speed ranges from 0.45 MPa to 45.30 MPa and from 0.012 m/sec to 0.12 (0.120)m/sec, respectively. The results show the mild to severe transition, which suggests the change of the wear mechanisms as a function of the pressure and sliding speed. The SEM micrographs of the corresponding worn area shows clearly that different wear mechanisms dominate.
