dc.description.abstractInvestigation of interaction residual stresses in substrates coated with thin WC-Co surface coated layers where the coefficients of thermal expansion between the substrates and coating are different and to different extents, have been performed with neutron diffraction. This systematic approach was followed with investigations performed on the reference grit-blasted substrates and their HVOF coated WC-Co products. Measurements were possible in both the 200 micro meter thick coatings and the substrates utilizing the KOWARI neutron strain scanner equipped with fixed slits. By means of precise gauge volume positioning of the sub-millimeter gauge volumes, stress gradients through the coated and non-coated substrates were measured and used to derive the coating stress conditions prevailing in the thin coating from the application of a stress balance (Stoney) approach. In addition, the average stresses in the 200 micro meter thick coatings were measured directly, by employing meticulous positional accuracy. Good agreement was obtained between the calculated and measured stress values in the coatings. Investigations were extended to determine the thermal nature of the residual stresses by studying the annealed counterpart samples as well. In this way the evolution of the residual stress upon annealing treatment was established.en_AU
