摘要：
Residual stresses affect significantly the quality and performance of thermally sprayed coatings. The residual stresses in alumina coatings were investigated by means of X-ray diffraction with Cr- and Cu-radiations. The sin(2) psi method could be applied to the evaluation of the stress fields. A very small stress gradient was indicated in surface layers of alumina coatings.
