Abstract [en]

Paper presents data on wear and friction of hot-pressed silicon nitride (HPSN) and its composites in contact with ball-bearing steel. The coefficient of friction under unlubricated sliding conditions was 0.45, and it did not change with load under lubricated conditions. The wear coefficient was the least for HPSN sintered with liquid in system containing yttria. HPSN containing 15 % of TiC showed the best wear resistance compared to HPSN with other concentrations of TiC or BN. No adhesive wear was detected.
