Friction and wear rate behaviour of dual phase steel plate specimens (DP600) sliding against corundum balls, as a function of sliding speed (0.01–0.25m/s) and contact frequency (1–16Hz), has been performed under bidirectional ball-on-plate (reciprocating motion) dry sliding wear tests where the plate specimen is studied. The wear mechanism is mainly oxidative. The coefficient of friction and the wear...
The reciprocating sliding wear behavior of high-silicon bainitic steels has been studied on microstructures obtained from two alloys containing 0.3 and 1.0wt% C, which were isothermally transformed between 200 and 425°C. Results show an order of magnitude improvement in the wear resistance of the nano-scaled bainitic structures with respect to the ultra-fine with similar hardness values. The scale...
This work presents a novel approach of sliding ball-on-disk wear tests where the disc material is investigated. Each part of the wear track on the disc is in discontinuous contact with the counterbody. The contact frequency at each part of the wear track on the disc with the counterbody is defined by the rotation frequency of the disc. The sliding speed is however a function of both the rotation frequency...
A pin-on-disk test apparatus was modified to decrease the degree of misalignment between the pin end and the disk counterface. This was achieved by separate alignment of both pin and disk. Disk alignment was allowed by incorporating a kinematic three-ball arrangement into the disk under-face. A self-aligning pin alignment system was introduced which did not require the perpendicularity of the pin...
