Friction and wear behaviour of dual phase steels in discontinuous sliding contact conditions as a function of sliding speed and contact frequency
© 2015 Elsevier Ltd. All rights reserved. Friction and wear rate behaviour of dual phase steel discs (DP600) as a function of sliding speed (0.05-3.75 m/s), and contact frequency (0.6-16.5 Hz) have been studied under unidirectional ball-on-disc dry sliding conditions. The coefficient of friction (CO...

| Sumario: | © 2015 Elsevier Ltd. All rights reserved. Friction and wear rate behaviour of dual phase steel discs (DP600) as a function of sliding speed (0.05-3.75 m/s), and contact frequency (0.6-16.5 Hz) have been studied under unidirectional ball-on-disc dry sliding conditions. The coefficient of friction (COF) and wear rate exhibit not only a highly dependence on the sliding speed, but also on the contact frequency which appears to be the key factor determining the wear behaviour of the DP600 even at constant sliding speed. The wear mechanism is mainly oxidative. The validity of Garcia-Ramil-Celis model is demonstrated for discontinuous sliding contacts at contact frequencies below 7 Hz. However, above 7 Hz, the disc behaves as if it were subjected to a continuous sliding contact. |
