Abstract
A lubricant has the formula X:Y, wherein X is a layered material selected from the group consisting of layered transition metal dichalcogenides and graphite. Y is a magnetic inclusion between layers of X. The lubricant is made by adding X to a solution containing ions of Y. The solution is continuously mixed and dried. The Y is then reduced to a metallic form.
Claims25
A lubricant having the formula:
- X:Y
- wherein X is a layered material with a graphite-like structure having unsaturated bonds at edges of particles thereof and Y is a magnetic inclusion between layers of X, Y having a magnetic field.
A lubricant having the formula:
- X:Y
- wherein
- X is a layered material selected from the group consisting of graphite and transition metal dichalcogenides having the formula AB.sub.2, wherein A is selected from the group consisting of Mo, W, Ti and Ta and B is selected from the group consisting of S and Se;
- and
- Y is a magnetic inclusion between layers of X, Y having a magnetic field.
A process for making a magnetic lubricant having the formula:
- X:Y
- wherein X is a layered composition and Y is a magnetic metal inclusion between layers of X, the process comprising the steps of:
- (a) adding X to a solution containing ions of Y;
- (b) mixing the solution and Y to form a mixture;
- (c) drying the mixture;
- and
- (d) reducing the Y to a metallic form.
A bearing having two surfaces in contact with each other and movable with respect to each other, at least one of the surfaces being of a ferromagnetic material, and a lubricant between the surfaces having the formula X:Y, wherein X is a layered material with a graphite-like structure having unsaturated bonds at edges of particles thereof, and Y is a magnetic inclusion between layers of X, Y having a magnetic field so the lubricant adheres to said at least one of the surfaces.
A lubricant, comprising:
- an oil or grease;
- and
- a powder mixed therewith, having the formula:
- X:Y
- wherein X is a layered material with a graphite-like structure having unsaturated bonds at edges of particles thereof and Y is a magnetic inclusion between layers of X, Y having a magnetic field.
