Triaxial residual stress distributions after local repair of practice-relevant components by means of cold gas repair spraying
Neutron stress mapping will be carried out at the instrument SALSA@ILL for cylincrical samples of Inconel 718 where a machined cavity was filled up by means of cold gas repair spraying. Two sample states will be considered, which differ by the process temperature, i.e. again, a ´cold´ and a ´hot´ condition will be compared. The edges are chamfered with an angle cutter to improve the gas flow and to achieve a better bonding during cold gas repair spray. Furthermore, in comparison to the first experiment (1-02-345) the spray process has been optimised to eliminate surplus material being deposited on undamaged surfaces around the repair site. We intend to focus on the cross section in the middle of the repair track, to analyse RS as a result of the optimised process control and the changed constraint imposed by the cylindrical sample. Here, the local in-depth distribution of RS is of particular interest (through the repaired region and about 1-2 mm below the interface), which is only accessible non-destructively with a satisfactory spatial resolution by means of neutron diffraction (using a small gauge volume defined by 0.6 mm FWHM radial collimators).
