Sammanfattning:Title screen
We studied experimentally the effect of nanosecond pulsed laser processing of silicon-carbide ceramic surface on tribological properties of its near-surface layer. Tribological properties were estimated using the friction coefficient, which was determined on the ball-on-disk tribometer at the reciprocating motion under normal stress conditions when the load changed from 1 to 5 N. We found that nanosecond pulsed laser processing of silicon-carbide ceramic surface changes the texture of its near surface layer. This texture was characterized by a lower friction coefficient, which was 20% less compared to that of unprocessed surface. A significant decrease in friction on the surfaces of silicon carbide ceramics increases the efficiency of devices that use surfaces of silicon carbide ceramics.
