Abstract

Spark plasma sintering is used to produce dense silicon nitride nanoceramics with titanium nitride additions and nanofiber-reinforced composites. The sintered nanocomposites demonstrate quite high mechanical properties (HV ≈ 14–16 GPa, K1c ≈ 4.8 MPa ⋅ m1/2) and low dry friction coefficient (f ≈ 0.65–0.68) and mass wear (~0.2–0.4 mg/km) in pair with ShKh15 steel. The nanocomposite strengthened with 3.8 wt.% silicon nitride nanofibers shows the most balanced mechanical and tribotechnical characteristics.
