A sliding engine component may include a sliding surface, and the sliding surface may include a plastic polymer-based layer disposed on a metallic substrate. The plastic polymer-based layer may have a composition including a plastic polymer-based material having distributed throughout the polymer-based material a thermochromic material configured to change color irreversibly when thermally activated by heating beyond a threshold thermal treatment condition. The polymer-based material may be cured.

Sliding engine component

A bearing element may include a bearing element substrate and a sliding layer applied to a surface of the bearing element substrate. The sliding layer may be formed of a sliding layer material. A surface roughness (Ra) of the surface of the bearing element substrate may be less than 1 &#x3bc;m. The sliding layer material may include a polymeric material and iron oxide. The sliding layer may have at least three layers of the sliding layer material.
