Spherical-Impact Damage and Strength Degradation in Silicon Nitrides for Automobile Turbocharger Rotors

Spherical‐impact damage to two silicon nitrides is investigated. Gas‐pressure‐sintered silicon nitride exhibits an elastic response to impact by spherical partially stabilized zirconia particles, resulting in Hertzian cone‐crack initiation in the sintered body. Pressureless‐sintered silicon nitride,...
