News & Innovations

Upgraded Coating for Large Bore EnginePiston Rings 

We are proud to introduce our new GDC60® coating which features a finer microstructure of the chrome matrix compared to the established GDC50 technology. During testing it demonstrated a further reduction of wear as well as lower friction and greater scuffing resistance. Federal-Mogul‘s well established GDC coatings are of galvanic nature, enabling use of the high coating thicknesses required for LBE's. As cylinder pressures increase, higher scuff resistance is required. With the development of GDC60 our engineers have overcome the challenge to maintaining the high robustness and cost-effective design advantages of GDC coatings, while at the same time meet the increasing demands in application. GDC60 offers a highly cost-effective answer which is convenient to implement, quick to validate, and can be used in combination with existing and well-proven design features. Please feel free to get in touch with us on Sea Japan and learn more about this key enhancement to our coating portfolio.
