the friction coefficient was determined at simulating the operating conditions of
sealing rings of gas-dynamic face seals. In contrast, the load applied to
the bearing is received by a very small contact area of the rolling
elements with raceways. Therefore, very high contact stresses occur in
the points of contact even at relatively moderate loads. The purpose of
this research is to determine a possibility of microstructuring the
surface of silicon carbide ceramic by pulse-periodic laser treatment for
reducing the friction losses in rolling bearings
