Beschreibung
Zusammenfassung:	Link chain (1) comprises chain parts (2,3) connected together at the chain links. Each chain link comprises a bolt (5) and a bearing (7) surrounding the bolt. The bolts have a boride layer on their outer peripheral surface and the bearings are made from a sintered material. The layer base of the boride layer facing the base material has a toothed structure. Preferred Features: The boride layer has a thickness of 15-70, preferably 30-20 microns . The boride layer contains Fe2B as the main component. A diffusion zone in the base material is joined to the toothed structure. The base material is made from case hardening steel, preferably 16MnCr5. The sintered material contains 1-4 % nickel, 1-3 % copper, 0.5-1.5 % molybdenum, 0.3-1.0 % carbon and a balance of iron. The bearing is impregnated with a lubricant.
