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=−550±40 MPa, showing that ND investigation is very suitable for critical applications, where a much greater stress situation could be prezent at a diverse depth.
