  • Method for boriding of coatings using high speed electrolytic process
    Patent number: 10287700
    Abstract: A method for producing a wear and corrosion resistant WC based material coated with one or more metals selected from group IVB, VB and VIB metals (according to CAS system) and Al is disclosed. The method comprises treating of said coated structure with electrochemical boriding treatment in an electrolyte which is substantially free of halogenated compounds wherein the electrolyte comprises alkali carbonates and boron sources and said electrolyte being heated during electrolysis under an induction heating regime having electromagnetic frequency ranging from 50 to 300 kHz during electrolysis.
    Type: Grant
    Filed: November 6, 2008
    Date of Patent: May 14, 2019
    Inventors: Mustafa K. Ürgen, Servet I. Timur, Kürsat M. Kazmanli, Güldem Kartal
  • Ultra-fast boriding of metal surfaces for improved properties
    Patent number: 8951402
    Abstract: A method of ultra-fast boriding of a metal surface. The method includes the step of providing a metal component, providing a molten electrolyte having boron components therein, providing an electrochemical boriding system including an induction furnace, operating the induction furnace to establish a high temperature for the molten electrolyte, and boriding the metal surface to achieve a boride layer on the metal surface.
