Abstract
A sliding engine component may include a sliding surface including a plastic polymer-based layer disposed on a metallic substrate. The plastics polymer-based layer may include a plurality of plastic polymer-based layers. The plurality of plastic polymer-based layers may include a first coating of a first polymer-based layer deposited on the metallic substrate and cured at a first temperature, and a second coating of a second polymer-based layer deposited onto the first polymer-based layer and cured at a second temperature. The second temperature may be lower than the first temperature.
Claims18
A sliding engine component comprising:
- a sliding surface including a plastic polymer-based layer disposed on a metallic substrate, wherein the plastic polymer-based layer includes a plurality of plastic polymer-based layers, and wherein the plurality of plastic polymer-based layers include:
- a first coating of a first polymer-based layer deposited on the metallic substrate and cured at a first temperature;
- a second coating of a second polymer-based layer deposited onto the first polymer-based layer and cured at a second temperature;
- wherein the second temperature is lower than the first temperature;
- and
- wherein the plurality of polymer-based layers have the same composition.
An engine comprising a sliding engine component including a plastic polymer-based layer on a metallic substrate, the polymer-based layer comprising:
- a first polymer-based layer deposited onto the metallic substrate and cured at a first temperature;
- and
- a second polymer-based layer deposited onto the first polymer-based layer and cured at a second temperature that is lower than the first temperature;
- wherein the first polymer-based layer and the second polymer-based layer have the same composition.
