Abstract
A sliding engine component may include a substrate having a surface coated with a first electroplated metallic layer and a second electroplated metallic layer. The first metallic layer may be disposed between the substrate and the second metallic layer. The first metallic layer and the second metallic layer may have a grained structure. The grained structure of each of the first metallic layer and the second metallic layer may have an aspect ratio between a mean grain size perpendicular to the substrate surface and a mean grain size parallel to the substrate surface. The aspect ratio of the second metallic layer may be less than the aspect ratio of the first metallic layer.
