Abstract
A foil bearing assembly for supporting a rotating member that rotates about an axis including a stationary mount member spaced from the rotating member so that a gap is defined between the stationary mount member and the rotating member. A foil member is disposed in the gap between the rotating member and the stationary mount member. At least one of the rotating member, the stationary mount member or the foil member includes a wear resistant coating layer.
Claims25
A foil bearing assembly for supporting a rotating member that rotates about an axis, the foil bearing assembly comprising:
- a stationary mount member spaced from the rotating member so that a gap is defined between the stationary mount member and the rotating member;
- and
- a foil member disposed in the gap between the rotating member and the stationary mount member to support the rotating member via a fluid film when the rotating member rotates,
- wherein at least one of the stationary mount member, the rotating member and the foil member includes a wear resistant coating layer formed of a refractory material including rhenium.
A foil bearing assembly for supporting a rotating member configured to rotate about an axis, the foil bearing assembly comprising:
- a stationary mount member spaced from the rotating member so that a gap is defined between the stationary mount member and the rotating member, the rotating member arranged for relative coaxial rotation with respect to the stationary mount member;
- a foil member disposed in the gap between the rotating member and the stationary mount member;
- wherein at least one of the stationary mount member, the rotating member and the foil member includes a wear resistant coating layer formed of a refractory material including a largest constituent being rhenium by atomic percent.
A foil bearing assembly for supporting a rotating member configured to rotate about an axis, the foil bearing assembly comprising:
- a stationary mount member spaced from the rotating member so that a gap is defined between the stationary mount member and the rotating member, the stationary mount member including a bore formed therein, the rotating member disposed within the bore and arranged for relative coaxial rotation with respect to the stationary mount member;
- and
- a foil member disposed in the gap between the rotating member and the stationary mount member;
- wherein at least one of the bore and the foil member includes a substrate and a wear resistant coating layer formed of a refractory material selected from a group consisting of elemental rhenium, a rhenium alloy, a rhenium nitride, rhenium boride and rhenium fluoride disposed on an intermediate bonding layer, the intermediate bonding layer disposed on a substrate material.
