Abstract

A sliding component, particularly a disk valve plate. The sliding component includes a multi-layer surface structure comprising a strengthening layer harder than the substrate material, and an amorphous diamond top layer.

Claims

AMENDED CLAIMS [Received by the International Bureau on 19 April 2005 (19.04.2005)
Original Claim 1 amended ; Claims 2-13 unchanged ; Original Claims 14-67 cancelled and replaced by new Claims renumbered 14-20 (3 pages) ] 1. A first component of a disk valve, said first component having a sealing surface in sliding contact with a second component of said valve also having a sealing surface, said sealing surface of said first component having a sufficiently smooth conformal sealing surface to substantially prevent transmission of a fluid between each of said sealing surfaces, characterized in that said first component comprises: a base material; a strengthening layer comprising a material harder than said base material, said strengthening layer having a thickness less than about 10 microns; and an amoφhous diamond layer disposed on said strengthening layer, said amoφhous diamond layer forming said sealing surface, and said amoφhous diamond layer having a thickness of at least a value sufficient to improve the wear resistance of said first component.
2. The component of claim 1 wherein said base material is selected from the group consisting of a glass, glass-ceramic, a glassy material, and a polymeric material.
3. The component of claim 1 wherein said base material comprises iron aluminide.
4. The component of claim 1 wherein said strengthening layer comprises DLC (diamond-like carbon).
5. The component of claim 1 wherein said strengthening layer comprises a superlattice structure.
6. The component of claim 1 wherein said strengthening layer comprises chromium nitride.
30
7. The component of claim 1 wherein said amoφhous diamond layer includes graphitic inclusions.
8. The component of claim 7 wherein said graphitic inclusions have a surface density of at least about 500/mm2.
9. The component of claim 1 wherein said base material is selected from the group consisting of stainless steel, aluminum, brass, titanium, zirconium, a cermet and a ceramic.
10. The component of claim 1 wherein said strengthening layer comprises a material selected from the group consisting of an oxide layer, a carbide layer, a carbo-nitride layer, and a nitride layer.
11. The component as defined in claim 1 wherein the thickness of said strengthening layer is about 500 nm to about 6 microns.
12. The component as defined in claim 1 wherein the thickness of said amoφhous diamond layer is about 100 to about 500 nm.
13. The component of claim 11 wherein said base material comprises stainless steel, said strengthening layer comprises chromium nitride, and the thickness of said amoφhous diamond layer is about 100 to about 500 nm.
14. The component of claim 1 wherein the amoφhous diamond layer further includes an average surface roughness which is not substantially higher than that of said strengthening layer, said amoφhous diamond layer including graphitic inclusions present in said surface.
15. The component as defined in claim 1 wherein the strengthening layer has a thickness of at least a value sufficient to improve the scratch resistance of said first and second components.
16. A method of forming a sliding component of a disk valve, having a base material, the method steps characterized by:
31 depositing a strengthening layer on the base material; and depositing by physical vapor deposition a smooth amoφhous diamond layer on the strengthening layer.
17. The method as defined in claim 16 wherein the temperature during the deposition of the strengthening layer and the amoφhous layer is less than about 200°C - 300°C, thereby avoiding any need to calculate predetermined mechanical and thermal properties of the base material, the strengthening layer and the amoφhous diamond layer.
18. The method as defined in claim 16 wherein the depositing step includes forming a graphite phase within the amoφhous diamond layer.
19. The method as defined in claim 16 wherein the step of depositing a smooth amoφhous diamond layer comprises forming a superlattice structure comprised of a plurality of amoφhous diamond layers.
20. The method as defined in claim 19 wherein the step of depositing a plurality of amoφhous diamond layers comprises forming a superlattice multi-layer with at least one layer of amoφhous diamond and another layer of different phase of diamond.
