Beschreibung
Zusammenfassung:	An adjustment interface inserted between a first part made of nickel or made of nickel alloy or made of cobalt-chromium alloy in relative motion with a second part made of nickel or made of nickel alloy or made of cobalt-chromium alloy. The interface includes a first adjustment layer on one of the two parts and has a composition that makes it possible, with the friction with the other part, to create a glaze-type layer. A second adjustment layer is deposited on the second part for cooperation with the first layer to act as a catalyst for the oxide formed by friction with the first layer. The first glaze layer of the interface improves the sliding of the parts under friction. The catalyst function provided by the second layer makes it possible to stabilize the oxide formed by friction and to thus ensure a lubrication function over an extended high-temperature range.
