Quantity friction and lubrication


Tribology is the study of friction, wear and lubrication. This assay is performed with a specifically designed attachment to quantify resistance of materials over a broad range of angular frequency (radians/sec) under a defined downward force (up to 40N (4.04kg)) and temperature (0 to 180C).  An example output are Stribeck curves (below) that compare the coefficient of friction (CoF) vs increasing spindle speed for 2 regular and 2 high mileage brand name motor oils at 15, 25, and 125C under 1 Newton (101 grams) downward force.
