Introduction to Tribology Testing
Taking advantage of the high lateral rigidity, high sensitivity and high stability of the Vantage™ system Micro Materials have developed a range of nanotribological modules including scratch, fretting and NanoTriboTest (reciprocating) tests and combined these with additional multi-sensing capability.
As single-asperity contacts, nanotribological tests provide unique insights into the roles of test severity and type, surface topography and mechanical properties on friction and wear. They enable individual mechanisms to be isolated and studied in-depth improving fundamental understanding of friction and wear mechanisms.
The full load range is available in all the tribology modules allowing tests to be performed over a wide range of contact pressures by changing the load and probe geometry.
This allows lab-scale replication of the widest possible range of real-world contact scenarios.
Typical conditions are shown in the table.
Reciprocating friction and wear testing with the NanoTriboTest has revealed extremely load- and cycle- dependent friction and wear behaviour on Ti6Al4V which was not found for 316L stainless steel.
At 50 mN the passive oxide on Ti6Al4V breaks with multi-cycling causing the underlying alloy to be exposed with dramatic increase in friction and reduction in wear resistance.
Nano-fretting experiments reveal how coatings degrade and ultimately fail cycle-by-cycle.
Clear failure during a 250-cycle test on a TiN coating on Si with 25 mN normal load, 5 µm radius diamond indenter, 80 µm track length, 10 µm/s velocity.
Includes comprehensive software package for visualizing how friction and energy dissipation change with sliding distance and wear.
