Abstract
A sliding material including: a substrate, and a textured sliding layer overlying the substrate, where the sliding layer includes asperities including a plurality of apexes and nadirs, where 1) the sliding layer has a root mean square gradient of less than 0.064; 2) the sliding layer has an apex material portion of less than 10%; 3) the sliding layer has a nadir material portion of less than 75%, and where the textured sliding layer induces formation of a film when engaged in a rotational interface w/ another component.
Claims19
A sliding material comprising:
- a substrate, and
- a textured sliding layer overlying the substrate, wherein the textured sliding layer comprises asperities comprising a plurality of apexes and nadirs, wherein the textured sliding layer has an apex material portion of less than 10% and a nadir material portion of less than 75%, wherein the textured sliding layer has a root mean square gradient of less than 0.064, and wherein the textured sliding layer induces formation of a film when engaged in a rotational interface with another component.
An assembly comprising:
- a first component;
- a second component;
- and
- a bearing located between the first component and the second component, the bearing comprising:
- a substrate, and
- a textured sliding layer overlying the substrate, wherein the textured sliding layer comprises asperities comprising a plurality of apexes and nadirs, wherein the textured sliding layer has an apex material portion of less than 10% and a nadir material portion of less than 75%, wherein the textured sliding layer has a root mean square gradient of less than 0.064, and wherein the textured sliding layer induces formation of a film when engaged in a rotational interface with another component.
