  • Chain element and method for the production thereof
    Patent number: 10174809
    Abstract: A chain element (2), in particular a chain pin (4), for joining at least two chain links (3), characterized in that it comprises a surface layer (5) containing boron and vanadium, formed by at least one step of diffusing boron and vanadium in the areas of the chain element (2) which are close to the surface. The surface layer (5) containing boron and vanadium is formed by boriding and subsequently vanadizing a substrate material having a carbon content of 0.60 wt.-% to 1.0 wt.-%.
    Type: Grant
    Filed: December 20, 2016
    Date of Patent: January 8, 2019
    Assignee: SCHAEFFLER TECHNOLOGIES AG & CO. KG
    Inventors: Monir Asgarpour, Christian Poiret
  • Chain element, chain pin, and method for producing same
    Patent number: 9958030
    Abstract: Chain element (2), particularly a chain pin (4) for joining at least two chain links (3), which element is formed from a base material (5) containing carbon, particularly steel, characterized in that it has a surface layer (7) containing boron and vanadium, wherein the surface layer (7) is produced by a method according to which, in a first method step, an intermediate layer (6) containing carbon and vanadium is formed by at least one measure for the diffusion of vanadium into surface regions close to the surface of the base material (5) and, in a subsequent second method step, the surface layer (7) is formed by the transformation of the intermediate layer (6) by at least one measure for the diffusion of boron into the intermediate layer (6).
