摘要：

It is known that the curvature change developed in a coated strip is an index for determining the residual stresses in coatings. This paper uses beam theory to derive closed-form solutions for the stress analysis. In addition to theoretical derivation, experimental measurements are performed on TiC coating/graphite substrate composites. The experimental results reveal the presence of residual tensile stress in TiC coatings.
