Abstract
The invention relates to a composite material which is to be used in sliding bearings and comprises a metallic support (1) and at least one reinforcement material having an open structure (2). Said support (1) and reinforcement material (2) are connected to each other by means of a metallic connection. An overlay (4) which is a polyethylene(PE)-based layer is provided on the reinforcement material (2) as an additional layer.
Claims28
A composite material comprising:
- a. a metallic inner support,
- b. at least one outer reinforcement material having an open structure
- c. an overlay layer provided on the outer reinforcement material, wherein the overlay contains polyethylene;
- d. a metallic connection between the outer reinforcement material and the inner support, the metallic connection being defined as an intermediate metallic layer galvanized and/or plated between the inner support and the outer reinforcement material.
1 more element
A composite material comprising:
- a. a metallic substrate,
- b. an outer layer of porous metallic reinforcement material, the outer layer having connections to the metallic substrate across the surface of the metallic substrate,
- c. a smooth intermediate metallic connecting layer galvanized and/or plated between the substrate and the outer layer, and
- d. an overlay layer situated in the pores of the outer layer, wherein the overlay layer contains polyethylene,
- wherein the outer layer and/or the overlay layer define the outer surface of a bearing.
2 more elements
A composite material comprising:
- a. a metallic substrate having an outer surface,
- b. a reinforcing layer of metallic material having:
- i. an inner surface facing the outer surface of the metallic substrate, and
- ii. an opposing outer surface which at least partially defines the outer bearing surface of a sliding structure, wherein:
- (1) voids are defined within a substantial portion of the reinforcing layer, and
- (2) the voids contain polyethylene;
- and
- c. an intermediate metallic connecting layer having:
- (1) an inner surface joined to the outer surface of the substrate, and
- (2) a smooth outer surface joined to the inner surface of the reinforcing layer.
