  • Patent number: 11571762
    Abstract: A printing method for selectively depositing braze powders on a surface comprises extruding a filament from a nozzle moving relative to a surface, where the filament comprises a flowable carrier mixed with a braze powder. As the nozzle moves, the filament is deposited on the surface in a predetermined pattern defined by the motion of the nozzle relative to the surface; thus, the braze powders are deposited at one or more predetermined locations on the surface.
    Type: Grant
    Filed: November 15, 2019
    Date of Patent: February 7, 2023
    Assignees: Rolls-Royce North American Technologies Inc., ROLLS-ROYCE CORPORATION

  • Publication number: 20230033578
    Abstract: The disclosure describes example techniques and assemblies for joining a first component and a second component. The techniques may include positioning the first and second component adjacent to each other to define a joint region between adjacent portions of the first component and the second component, the joint region being coated with an adhesion resistant coating. The techniques may also include positioning a braze material in the joint region, heating the braze material to form an at least softened material, and cooling the at least softened material to form a mechanical interlock including the braze material in the joint region joining the first and second components. The braze material does not metallurgically bond to the joint surface.

  • Patent number: 11565336
    Abstract: A method for selectively adhering braze powders to a surface comprises applying a braze powder to a surface, and then directing a laser beam onto the braze powder while the laser beam moves along a predetermined path relative to the surface. The laser beam selectively heats the braze powder along the predetermined path such that the braze powder is sintered and bonded to the surface. Thus, a braze deposit is formed at one or more predetermined locations on the surface. After forming the braze deposit, excess braze powder, that is, the braze powder not selectively heated by the laser, is removed from the surface.

  • Patent number: 11420279
    Abstract: A method for selectively adhering braze powders to a surface comprises applying a binder material to a surface, depositing a braze powder on the binder material, and then directing a laser beam onto the braze powder while the laser beam moves along a predetermined path relative to the surface. The laser beam selectively heats the braze powder and the binder material along the predetermined path such that the binder material is removed and the braze powder is sintered and bonded to the surface. Thus, a braze deposit is formed at one or more predetermined locations on the surface. After forming the braze deposit, excess braze powder and binder material, that is, the braze powder and binder material not selectively heated by the laser, are removed from the surface.
