Residual stress values calculated from laboratory (Lab) and synchrotron (EDDI) data (Fig. 4) using equations (3)–(5) for non-blasted (0b) and blasted (4b) coatings. represents the fitted stress profile [equation (7)] in the Laplace space in the blasted coating as a function of . represents the recalculated stress profile [equation (6)] in real space. and were determined by using both Lab and EDDI data, except for the three EDDI measurement points at in the range 0–2 µm. For the non-blasted sample the stresses are relatively homogeneous across the coating.
