Transformation of the Stressed State of a Surface Layer of Nitride Ceramic with a Change in TiC-Coating Thickness. Loading Version — Concentrated Force Load

Resumo

The effect of titanium carbide coating thickness on transformation of the stressed state of a surface layer of Si₃N₄–TiC–Y₂O₃-ceramic under action of a concentrated force is studied. It is established that an increase in TiC-coating thickness leads to an increase in stresses σ₁₁, σ₂₂, σ₁₂ and stress intensity σ_i within a nitride ceramic surface layer.
