摘要：

Formulas based on the beam theory are derived for calculating the in‐plane elastic modulus and residual stresses in ceramic coatings. In addition to theoretical derivation, experimental data for SiC coating/graphite substrate composites are proposed. The results indicate that the modulus of SiC coatings is 359 GPa. The residual stresses are in compression and are functions of the ratio of substrate thickness to coating thickness. Copyright © 1990, Wiley Blackwell. All rights reserved
