This application note shows how the MFT-5000 can be used to study materials, coatings and lubricants in linear wear friction testing setup. The test covers a laboratory procedure for determining the wear and friction of materials, liquid and lubricants etc. during sliding using a pin on plate tribometer or ball on flat tribometer setup.
● Temperature upto 1200C
● Stroke upto 35mm, 50Hz frequency
● Dry and Liquid Tests
● Piezo sensors for high frequency friction measurements
The state of the art Rtec Multi Function tribometer Mft-5000 is globally regarded as the most versatile and technologically advanced tribometer. The patented integrated 3D profilometer allows to analyse surface change vs time makes it usable for many application across various industries. In addition it comes with patented force sensors (piezo, capacitive & strain gauge) with ultra low resolution, highest speeds, stable torque and widest load range than any other commercially available tribometer.
MFT-5000 verstatily allows to mount several test/application specific modules on same platform. Please visit following links to learn more - Pin on Disk Tribology, Product page, Main Applications
The linear reciprocating tribometer pushes a stationary pin or ball to press against the oscillating plate at a determined force and moves it in a linear reciprocating manner at the set frequency. During the test coefficient of friction (COF), friction force, wear and several other parameters are measured and reported. Figure shows the top view of the set up for lubricant container in which samples can be tested in lubricated conditions.
Figure shows the friction curve from a typical reciprocating test. The change in friction values from negative to positive corresponds to the change in direction during the test. The data can be collected up to 5000 points per second. Several other channels such as temperature, coefficient of friction, wear etc. can also be recorded during the test. The high-end electronics and the high data acquisition rates makes it possible to get useful insights in the test including the static to dynamic peaks as the test changes direction.
Rtec multi-function tribometer comes with an optional inline 3D Profilometer. The profilometer automatically measures the surface topography of the wear track at intervals defined by the user e.g. after a certain number of cycles, duration of time or at the on-set of an event such as increase in friction. The XY stage is equipped with advanced encoders to automatically move the sample between the test and image area. The ability to characterize the change in surface topography and wear track with time and combining it with friction data makes the analyses extremely powerful.
