  • Process for the electrolytic polishing of a metallic substrate
    Patent number: 11162185
    Abstract: The present disclosure is directed a process for the electrolytic polishing of a metallic substrate, including the steps of (i) providing an electrolyte in an electrolytic cell having at least one electrode, (ii) disposing a metallic substrate as an anode in the electrolytic cell, (iii) applying a current at a voltage of 270 to 315 V from a power source between the at least one electrode and the metallic substrate, and (iv) immersing the metallic substrate in the electrolyte, wherein the electrolyte includes at least one acid compound, at least one fluoride compound, and at least one complexing agent.
    Type: Grant

    Date of Patent: November 2, 2021
    Assignee: Airbus Defence and Space GmbH
    Inventors: Sarah Bagehorn, Tobias Mertens
  • A Method For The Surface Finishing Of Metals And Alloys
    Publication number: 20190292681
    Abstract: An electrolyte (EL) for the electrolytic polishing of a metallic substrate includes at least one fluoride compound (F) and/or one chloride compound (Cl), and at least one complexing agent (CA), wherein the electrolyte (EL) does not contain an acid compound that is not a complexing agent. Furthermore, a process for the electrolytic polishing of a metallic substrate wherein the electrolyte (EL) is applied is described.
