... 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...

... the coefficient of friction (COF) of rubber incorporated with CNTs oriented in different directions. The macroscale and nanoscale results qualitatively show good agreement. The COF and wear rate of CNTs-z/rubber are both lower than that of CNTs-x/ and CNTs-y/rubbers. That is, CNTs perpendicular to the sliding...

... reinforcement composition has shown a superior wear resistance compared with all other clad layer composite compositions. The improvement in the wear resistance achieved with (Al 2 O 3 + TiN)/Ti6Al4V composite clad layer deposition at 2.5 m/s, 3.5 m/s, and 4.5 m/s sliding velocities is 56.60%, 63.26%, and 68.53...

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...
