Description	The residual stress (RS) induced in the substrateby thermal spray-coating was studied. Two 3Cr4Ni inoxidizable martensitic steel samples, one having a thermal spray (WC–12%Co) HVOF coated surface, the other a shoot peened surface,were analyzed byneutron diffraction (ND) in order to determine the real RS depth-proﬁle and investigate the effects of the thermal process on the considered materials. The stresses resulted in the range from 80 to 50 MPa for the uncoated sample, while for the coated sample they increased gradually from a slight compressive status in correspondence of the uncoated surface, to greatest values of 250 MPa in correspondence of the coating. A traditional X-ray investigation on the coated surface measured compressive RS values σ=55040 MPa, showing that ND investigation is very suitable for critical applications, where a much greater stress situation could be prezent at a diverse depth.
