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 borizing and subsequently vanadizing.
Claims10
Chain element (2), in particular a chain pin (4), for connecting at least two chain links (3), characterized in that it comprises a surface layer (5) that contains boron and vanadium and is formed by at least one measure for diffusion of boron and vanadium into areas of the chain element (2) that are close to the surface.
Chain element according to one of the preceding claims, characterized in that the surface layer (5) containing boron and vanadium has a layer thickness from 10 to 350 μm, preferably from 100 to 300 μm, especially preferred from 150 to 250 μm.
Chain pin (4) for connecting at least two chain links (3) of a chain (1), characterized in that it comprises a surface layer (5) that contains boron and vanadium and is formed by at least one measure for diffusion of boron and vanadium into areas of the chain pin (4) that are close to the surface.
Method for the production of a chain element (2), in particular a chain pin (4), for connecting at least two chain links (3), with a surface layer (5) containing boron and vanadium, characterized by the steps:
- preparation of the chain element (2),
- performance of at least one measure for diffusing boron and vanadium into areas of the chain element (2) that are close to the surface for construction of the surface layer (5) containing boron and vanadium.
