Ball-on-flat test: The ball-on-flat test is a method used to evaluate the wear characteristics and frictional properties of materials under controlled conditions. This test typically involves a spherical specimen (the ball) making contact with a flat surface, allowing for the study of tribological interactions, including wear mechanisms and friction coefficients.

1.1 This test method covers laboratory procedures for determining the sliding wear of ceramics, metals, and other candidate wear-resistant materials using a linear, reciprocating ball-on-flat plane geometry. The direction of the relative motion between sliding surfaces reverses in a periodic fashion such that the sliding occurs back and forth and in a straight line.
Historical/Traditional Test Geometry. The classic work of Thurston 1, Martens 2, Stribeck 3 and Hersey 4 were done using a journal-bearing geometry, which possesses all of the above requirements (Figure 3). An instrumented journal-bearing test allows for evaluation of the friction over a range of relative velocities and/or loads. Aiming at the friction and wear experiment requirements for different solid materials under different conditions, a new reciprocating friction and wear tester is proposed. In the lubrication state, graphite can also improve the friction performance. Graphite is prone to fall off during friction, resulting in the formation of pits on the wear scar surface. These pits can store more lubricating oil and improve friction performance under starved lubrication conditions [31].Bruker’s High Frequency Reciprocating Rig (HFRR) Module for the UMT TriboLab™ Mechanical Tester enables a versatile and cost-effective way to screen lubricants and materials at the benchtop scale. Traditionally, the .
