Abstract

The effect of titanium carbide coating thickness on transformation of the stressed state of a Si₃N₄–TiC–Y₂O₃-ceramic surface layer under action of heat flow is studied. It is established as a result of numerical experiments that an increase in TiC coating thickness from 5 to 15 μm, applied to nitride ceramic, leads to a reduction in ceramic temperature, and increase in σ₁₁, σ₂₂, σ₁₂, and σ_i, and indices of their structural inhomogeneity in a ceramic surface layer.
