  • Joined incompatible metallic parts and method of joining
    Patent number: 10724561
    Abstract: A technique for joining parts of incompatible metals involves cold spraying a 150-900 micron thick layer of a metal compatible with the second part onto the first part, and friction stir joining the parts by lap welding while keeping a tool of the FSJ tool at least 300 microns away from the first part (less layer) throughout the joining, to avoid damaging the cold spray to first part interface, and formation of intermetallics. Fatigue resistance was tested, with and without a sealant.
    Type: Grant

    Publication number: 20180221985
    Abstract: A technique for joining parts of incompatible metals involves cold spraying a 150-900 micron thick layer of a metal compatible with the second part onto the first part, and friction stir joining the parts by lap welding while keeping a tool of the FSJ tool at least 300 microns away from the first part (less layer) throughout the joining, to avoid damaging the cold spray to first part interface, and formation of intermetallics. Improved fatigue resistance is shown. A sealant can advantageously further improve fatigue resistance.
