  • Publication number: 20230294236
    Abstract: A method for modifying the mechanical and surface properties of a component. The method involves: removably attaching a component to at least one component support that is located within a vibratory trough of a component treatment apparatus, the at least one component support being a support shaft upon which the component is removably mountable within the vibratory trough; supplying the vibratory trough with treatment media; moving the component support or the vibratory trough so that the component is immersed into the treatment media; vibrating the vibratory trough to provide a substantially uniform surface treatment of the component, the vibratory trough being movable by at least one trough vibrating mechanism whose actuation is controlled by a controller in response to signals received from at least one sensor located on or within the vibratory trough; removing the component from the treatment media; and detaching the component from the component support.

  • Publication number: 20220161387
    Abstract: A method and apparatus for finishing a surface of a component. The method includes installing the component in an apparatus configured to deliver a flow of abrasives to the surface and to generate cavitation bubbles in a liquid contacting the surface using a cavitation generator that includes an ultrasonic generator configured to generate cavitation bubbles in the liquid contacting the surface by ultrasonic excitation in the liquid or a laser configured to generate cavitation bubbles in the liquid contacting the surface by laser excitation in the liquid; controlling the cavitation generator such that cavitation bubbles are generated to finish the surface by implosion of the cavitation bubbles; and controlling the flow of slurry to the surface so as to finish the surface by abrasion. An apparatus for finishing a surface of a component is also disclosed.

  • Patent number: 11123840
    Abstract: A method and apparatus for finishing a surface of a metal component made by additive manufacturing are provided. The method comprises: containing the component 41 in a fluid 43 that comprises abrasive particles 48; and generating pressure fluctuations that produce acoustic cavitation in the fluid by applying ultrasonic vibration into the fluid by an ultrasonic horn 45, thereby removing material from the surface of the component by a combination of cavitation bubble collapse on the surface and the striking of the surface by abrasive particles 48 accelerated by cavitation bubble collapse.

  • Publication number: 20190308292
    Abstract: There is disclosed a method and apparatus for finishing an internal channel of a component. The method comprises installing the component in a flow circuit which is configured to drive a fluid flow through the internal channel and controlling the fluid flow through the internal channel so that cavitation bubbles are continuously generated by a hydrodynamic effect to erode the internal channel by implosion of the cavitation bubbles. The fluid flow may comprise abrasive media which may abrade the internal channel.
