Summary

A method of calculation is described that relates the compressive stress in a ceramic coating that is bonded to a metal substrate to the strength of the ceramic-metal bond. Results are presented for calculations of the effect of the rate of heat transfer in developing thermal compressive stress in the ceramic, which results in separation of the ceramic from the metal at either the bond interface or the ceramic. Calculations are presented for the relation between ceramic thickness and compressive stress resulting from thermal gradients.
