Micro Tribometer Facility


Wear of materials is one of the most important causes of failure of components like acetabular cup and ball etc. A detailed study of the principles of friction, wear and lubrication i.e. the tribological properties, is necessary to certify a material as a potential body implant. With the above intention a pin on disk tribometer set-up (Fig. 1) was procured from Nanovea Inc. USA.

Unique features:

Following are the main features of the micro tribometer:




  • Continuous force vs. coefficient of friction plot (Fig. 2)

  • Depth sensor based on white light instead of laser that provides much more accurate depth profile of worn sample

  • Speed from 0.1 to 2000 rpm

  1. Provides three lubrication modes: Using a low pressure pulverization module, air is compressed and filtered then mixed with liquid to create a uniform spray that can be directed to the appropriate test zone.

  2. A drop by drop lubrication with flow control

  3. The soak option performs friction tests and wear tests under fluid in a specialized cup surrounding sample holder, allowing full submersion of the sample.
