Al-Haddad, A. A. and Salih, Nbhan D. and Wen, Chin Chee and Yusaf, T. F. and Yousif, B. F. (2010) New technique measuring film thickness for tribological machines. In: ASME 2009: International Mechanical Engineering Congress and Exposition, 13-19 Nov 2009, Lake Buena Vista, FL. USA.
In the present work, a prototype machine was developed for film thickness measurement for tribological tests. The configuration of the machine was based Block on Ring (BOR) technique. In the current machine, frictional forces and film thickness were measured using load cell and strain gauges, respectively. Calibration was made to determine the real film thickness. Experiments were conducted using the newly developed machine to investigate the film thickness during sliding of UHMWPE against aluminum alloy counterface. The tests were performed at applied loads (1.47 N - 2.94 N). The results revealed that increases the applied load reduces the film thickness which in turn played a main role in controlling the surface characteristics of the polymer.
