Abstract
A sliding element for an engine may include a metallic substrate, a first polymer-based layer, and a second polymer-based layer. The first polymer-based layer may include a polymeric material and may be disposed on the metallic substrate. The second polymer-based layer may include a polymeric material and may be disposed on the first polymer-based layer. The polymeric material of the first polymer-based layer may be the same as the polymeric material of the second polymer-based layer. The second polymer-based layer may further include a tungsten disulphide particulate.
