Abstract

The present paper aims to assess the friction coefficients obtained with pin-on-disc tests against those acquired in mechanical processing of materials, under similar conditions of surface texture and to evaluate the role of the mechanical properties of the pin-on-disc tribo-pairs in the overall frictional behaviour. It is shown that pin-on-disc tests, when performed with an adequate control of surface texture, are capable of providing a good estimate of the average value of the friction coefficient in mechanical processing applications and, in certain cases, when the tribo-pairs have similar mechanical properties, the value of the friction coefficient is independent of surface morphology.
