The apparatus allows a pin to rub on an oscillating disc whilst friction force and pin wear are recorded continuously. Tests have been performed over the load range 0–4·5 kgf at a constant speed of oscillation (8 c/min) and a constant amplitude (approximately 5·0 cm). Transitions are observed in the ‘friction force-load’ and ‘average wear rate–load’ relationships, the slope of the latter changing by a factor of about 30 at a critical load. The wear debris has been studied using the X-ray diffraction technique, and the rubbed surfaces have been examined using a Talysurf instrument and optical and electron microscopy.
