Tribological performance of surface with different wettability under ball-on-disc test

The surface wettability of friction pairs influences the tribological performance significantly. According to the results in this paper, under the ball-on-disc configuration, the lyophobic bottom surface is an effect way to reduce friction and wear compared to lyophilic surfaces. The robust lyophobic layer fabricated using laser under the fluorinated solution (i.e., RLMS sample in the figure) effectively reduces the friction and wear compared to the lyophobic surface fabricated using the traditional method (i.e., LMS sample in the figure).
