Tribotester was designed so that the axes of rotation of the two cylindrical surfaces of the friction are skew.

The tribological properties of sliding wear (reciprocation) for the different samples were evaluated in air on a tribometer equipped with tribotester software according to the standards: ISO 7148, ASTM G99-95a, ASTM G 133-95, with a relative humidity of 33 to 38%, a temperature of 24 to 27[degrees]C and a non-lubricated state.
[23], using a ball-on-disk tribotester, measured a friction coefficient between 0.2 and 0.6 for different nitrogen-implanted AISI 316L grades.
The speed of the roller and the duration of tests can be controlled via a computer attached to the tribotester.
The tribological behavior of the oxide graphene nanosheets as water-based lubricant additive was investigated using a UMT-2 ball-plate tribotester. With the addition of GO nanosheets in pure water, the antiwear ability was improved and the friction coefficient was decreased.
