Abstract
A bearing lining has a bearing backing layer provided with a coating comprising a first overlay layer and a second overlay layer, the first overlay layer being provided between the bearing backing layer and the second overlay layer. The first and second overlay layers each comprise a matrix material and a soft-phase material that is substantially insoluble in the matrix and dispersed within the matrix as soft-phase particles. The first overlay layer comprises a higher proportion by weight of a grain size reduction additive than the second overlay layer.

A bearing lining having a bearing backing layer provided with a coating comprising a first overlay layer and a second overlay layer, the first overlay layer being provided between the bearing backing layer and the second overlay layer, the first and second overlay layers each comprising a matrix material and a soft-phase material that is substantially insoluble in the matrix and dispersed within the matrix as soft-phase particles, and wherein the first overlay layer comprises a higher proportion by weight of a grain size reduction additive than the second overlay layer.
A bearing lining obtainable by the process of manufacturing a bearing lining comprising sputter depositing a first overlay layer directly or indirectly onto a bearing backing layer, sputter depositing a second overlay layer directly onto the first overlay layer, the first and second overlay layers each comprising a matrix material and a soft-phase material that is substantially insoluble in the matrix and dispersed within the matrix as soft-phase particles, and wherein the first overlay layer comprising a higher proportion by weight of a grain size reduction additive than the second overlay layer.
