Abstract
(DE)
Die Erfindung betrifft ein Gelenklager (1), umfassend ein metallisches erstes Lagerelement (2) aus Stahl, welches zumindest partiell mittels einer Beschichtung (5) beschichtet ist, ein metallisches zweites Lagerelement (3) aus Stahl, welches mit einem PTFE enthaltenden Gleitbelag (6) beschichtet ist, wobei die Beschichtung (5) und der Gleitbelag (6) in Gleitkontakt stehen, und wobei die Beschichtung (5) mindestens eine, auf dem ersten Lagerelement (2) mittels eines PVD-, CVD- oder PECVD-Verfahrens abgeschiedene erste Schicht (9) umfasst, wobei die Beschichtung (5) weiterhin mindestens eine, auf der mindestens einen ersten Schicht (9) angeordnete und dem ersten Lagerelement (2) abgewandte weitere Schicht umfasst.
(EN)
The invention relates to a pivot bearing (1) comprising a metal first bearing element (2) made of steel and coated at least partially by a coating (5), a metal second bearing element (3) made of steel and coated with a PTFE-containing sliding lining (6), wherein the coating (5) and the sliding lining (6) are in sliding contact, and wherein the coating (5) has at least one first layer (9) deposited on the first bearing element (2) by means of a PVD, CVD or PECVD method, wherein the coating (5) also has at least one further layer arranged on the at least one first layer (9) and facing away from the first bearing element (2).
(FR)
L'invention concerne une articulation à rotule (1), comprenant un premier élément (2) métallique en acier, lequel est revêtu au moins en partie au moyen d'un revêtement (5), un deuxième élément (3) métallique en acier, lequel est revêtu d'une garniture de glissement (6) contenant du PTFE, le revêtement (5) et la garniture de glissement (6) étant en contact glissant, et le revêtement (5) comprenant au moins une première couche (9) déposée sur le premier élément (2) d'articulation au moyen d'un procédé de dépôt physique en phase vapeur, de dépôt chimique en phase vapeur ou de dépôt chimique en phase vapeur assisté par plasma, le revêtement (5) comprenant en outre au moins une autre couche disposée sur la ou les premières couches (9) et opposée au premier élément (2) d'articulation.
