The parameters i.e. applied load, sliding velocity, sliding distance, and reinforcement content are treated as inputs, whereas the wear rate and coefficient of friction are considered as output variables for the tribological experimentation. The influence of various input process parameters on the tribological...

... coatings showed enhanced hardness, scratch and galling resistance at room temperature. Tribological tests were carried out under two contact conditions, i.e., sliding contact for galling resistance and reciprocating wear studies. The PU-based nanocomposite coatings showed enhanced galling resistance...

... tests were performed at room temperature using a reciprocating tribometer at a sliding speed of 1 m min −1 against a 6-mm diameter ZrO 2 ball. When sliding in air, the friction coefficient of Cu-based BMG decreases with the applied loads (5 N, 10N, and 20 N), and the wear behavior is mainly affected...

And there exists a clear distinction in the friction and wear behavior when the alloy sliding against different counterparts at RT–500 °C. The tribological properties of the alloy depend on the counterparts at RT–200 °C due to that the main wear...

... and microstructure studies. The wear tests were carried out under ASTM G99-05 standards through a pin-on-disc wear test device, exerting three different loads (10 N, 20 N, and 30 N) and using four different sliding distances (500 m, 1000 m, 1500 m, and 2000 m). As a result of the studies, it was observed...
