Biotribology and STLE exhibition Success
Papers were presented by Dr Marc Ingram at both conferences which were well received. If you would like a copy of either presentation, then please email: firstname.lastname@example.org
At The Biotribology Conference
Biotribology testing techniques by M. Ingram, PCS Instruments, UK
Investigating Scuffing Using a New Test Method by M. Ingram, C. Hamer, PCS Instruments, London, United Kingdom, H. Spikes, Imperial College, London, United Kingdom
Scuffing can occur in high sliding speed/high load contacts, during a breakdown of both the hydrodynamic and boundary films. The unprotected metal-metal contact that ensues exhibits high friction as the surfaces are momentarily welded and torn apart. A new testing method has been designed that can aid in the fundamental study of scuffing and screen the scuffing performance of formulated lubricants. The new testing method uses a high pressure, contra-rotating contact which accelerates the onset of scuffing in a controlled manner. The occurrence of scuffing is easily identified by a large change in the measured friction coefficient, and can then be classified in terms of the sliding speed or applied load at failure, which can be increased step-wise or linearly.
