Nitride Ceramic Surface Layer Stressed State Transformation with a Change in TiC-Coating Thickness. Stress – Distributed Force Load Version

Resumo

As a result of conducting numerical experiments a complex effect is revealed for titanium carbide coating thickness on the change in stressed state of a Si₃N₄–TiC–Y₂O₃-ceramic surface layer under action of a distributed force. It is established that an increase in TiC-coating thickness leads to an increase in σ_i inhomogeneity and an ambiguous change in σ₁₁, σ₂₂, and σ₁₂ inhomogeneity within a nitride ceramic surface layer.
