An OEM piston manufacturer applies various coatings to improve performance and life. The skirt coating from an OEM piston manufacturer contains molybdenum disulfide to reduce friction. During initial run‑in, this OEM piston manufacturer’s coating transfers to the cylinder wall.

A hard anodized layer on the crown helps an OEM piston Manufacturer resist micro‑welding. Thermal barrier coatings from an OEM piston manufacturer keep heat in the combustion chamber. The pin bore of an OEM piston manufacturer may receive a diamond‑like carbon coating.

For boosted engines, an OEM piston manufacturer uses a polymer coating on the skirts to prevent galling. The ring grooves from an OEM piston manufacturer can be anodized to resist micro‑welding. Some OEM piston manufacturers also offer phosphate coating for corrosion protection during storage.

Each coating process at an OEM piston manufacturer is validated with wear testing. The application thickness is controlled by automated spray or dip lines. After coating, the OEM piston manufacturer checks adhesion with a cross‑hatch test.

By choosing the right coating, an OEM piston manufacturer tailors pistons for specific fuels and loads. The lab at an OEM piston manufacturer simulates millions of cycles on coated samples. Ultimately, these surface treatments from an OEM piston manufacturer reduce friction and extend engine life. Collaborating with an OEM piston manufacturer early in design ensures coatings are properly applied.
