Abstract
A sliding component including a sliding layer, and an intermediate component including at least one undercut portion, the intermediate component coupled to the sliding layer, wherein the intermediate component has a thickness, T, and wherein an exposed thickness, TE, of the intermediate component is less than T. A method of forming a sliding component including providing an intermediate component including at least one undercut portion, the intermediate component having a thickness, T, and coupling a sliding layer to the intermediate component, wherein the intermediate component is partially embedded into the sliding layer, and wherein an exposed thickness, TE, of the intermediate component is less than T.
Claims20
A sliding component comprising:
- a sliding layer comprising a first major surface and a second major surface spaced apart by a thickness, wherein the first major surface can lie along a first plane and the second major surface can lie along a second plane such that the first and second planes do not intersect at any location therealong;
- and
- an intermediate component comprising an embedded portion within the sliding layer, and an exposed portion external to the sliding layer, the exposed portion comprising at least two undercut portions having an angle less than 90° with respect to the second major surface of the sliding layer, the intermediate component coupled to the sliding layer, wherein the intermediate component has a thickness, T, and wherein an exposed thickness, TE, of the intermediate component is less than T, wherein the intermediate component comprises a material having a yield strength of no greater than 500 MPa, wherein the undercut portions of the intermediate component forms cavities, wherein the cavities are at least partially defined by the second major surface of the sliding layer and the intermediate component, and wherein at least two of the undercut portions have different angles.
A bearing comprising:
- a sliding layer comprising a first major surface and a second major surface spaced apart by a thickness, wherein the first major surface can lie along a first plane and the second major surface can lie along a second plane such that the first and second planes do not intersect at any location therealong;
- a substrate;
- and
- an intermediate component comprising an embedded portion within the sliding layer, and an exposed portion external to the sliding layer, the exposed portion comprising at least two undercut portions having an angle less than 90° with respect to the second major surface of the sliding layer, the intermediate component disposed between the sliding layer and the substrate and partially embedded into each of the sliding layer and the substrate, wherein the intermediate component comprises a material having a yield strength of no greater than 500 MPa, wherein the undercut portions of the intermediate component forms cavities into which the substrate flows, wherein the cavities are at least partially defined by the second major surface of the sliding layer and the intermediate component, and wherein at least two of the undercut portions have different angles.
A method of engaging a sliding layer and a substrate together comprising:
- providing a sliding component including a sliding layer comprising a first major surface and a second major surface spaced apart by a thickness, wherein the first major surface can lie along a first plane and the second major surface can lie along a second plane such that the first and second planes do not intersect at any location therealong, and an intermediate component partially embedded in the sliding layer, wherein the intermediate component comprises an embedded portion within the sliding layer, and an exposed portion external to the sliding layer, and the exposed portion comprises at least two undercut portions having an angle less than 90° with respect to the second major surface of the sliding layer;
- and
- applying the sliding component and substrate relative to one another such that the exposed portion of the intermediate component at least partially embeds within the substrate, wherein the intermediate component comprises a material having a yield strength of no greater than 500 MPa, wherein the undercut portions of the intermediate component forms cavities into which the substrate flows, wherein the cavities are at least partially defined by the second major surface of the sliding layer and the intermediate component, and wherein at least two of the undercut portions have different angles.
