Residual stresses in plasma-sprayed Al2O3 layers were investigated by
means of X-ray diffraction with Cr and Cu radiation. No stress gradien
t was indicated in the surface layers of the alumina coatings within t
he range of the penetration depth of the applied radiation. Different
stress values were obtained by a high speed drilling method.
