Abstract
Due to its low density, high strength and high modulus, Si3N4 is a potential candidate as a wear resistant material. However, the fracture toughness of Si3N4 is rather poor. It is well known that the fracture toughness of ceramics can be increased by introducing compressive residual stress at the surface. Improvement of wear resistance of Si3N4 by surface modification with Al2O3 has been demonstrated. The strengthening of polycrystalline Si3N4 by producing compressive stresses at all grain boundaries throughout the sample was studied.
