Silicon nitride (Si 3 N 4 )-based ceramics are useful materials for tribological purposes due to their superior mechanical properties. One of their applications is as mechanical face seals. However, Si 3 N 4 rings failed as self-mated systems, leading to fluid leakage and catastrophic failure under
