PCS Instruments MTM2 - Southwest Research Institute

PCS Instruments MTM2
Mini Traction Machine
S
outhwest Research Institute® (SwRI®), recognized
worldwide as a leader in fuels and lubricants research,
utilizes the PCS Instruments MTM2 Mini Traction Machine
to investigate the frictional response and wear properties
of materials and lubricants. The computer-controlled test
provides in-test control of speed, load and temperature.
The disc and the ball/barrel can be rotated at different
speeds, giving slide roll ratios from 0 to 100%.
Electrical contact potential can be measured during the
test to obtain an indication of the presence of lubricant
and chemical films.
Standard test components are commonly used. However,
the balls or pins and discs can be manufactured from
materials of the components under investigation and
these components can then be coated, hardened,
surface-finished and/or textured as desired.
Post-test wear scar analysis and component surface film
analysis offer more in-depth understanding of wear
mechanisms and component/additive interactions. Both
are available at SwRI.

PCS Instruments modified the MTM2 for SwRI to provide
additional capabilities including extended temperature
range, extended load range, pin-on-disk attachment, disc
reciprocating mode and real-time wear measurement.
