Federal-Mogul Powertrain introduces high performance polymer bearing coating IROX 2

Wiesbaden, Germany, September 6, 2018 – Following the launch of the IROX®2 for light-duty engine bushings last year, the Federal-Mogul Powertrain will be launched at the Hannover 2018 IAA Commercial Vehicles Exhibition for heavy-duty vehicle applications New high performance polymer coating. IROX® 2 enhances anti-seizure and anti-fatigue properties, especially for steel crankshafts. As part of the Huimen IROX technology, IROX® 2 not only reduces friction, improves efficiency and wear resistance, but also supports the use of low viscosity oils. The IROX® 2 for light-duty engines has been mass-produced. After a series of successful tests, the first batch of heavy-duty vehicles have been designated for use.

“IROX® 2 extends the fatigue load range to around 100 MPa, and previously expensive FPD coated bushings were required to achieve the same level of fatigue loading,” said Gian Maria Olivetti, CTO of Federal-Mogul Powertrain. Friction, the innovative IROX bearing coating also helps customers reduce fuel consumption and CO2 emissions. We evaluated it using an in-house specially developed test rig. The results show that after IROX coated bushings, the friction loss is higher than that from 5W30 oil. The amount of friction loss when it is 0W20 oil."

IROX is specially developed for crankshafts with a standard surface finish, while IROX® 2 is suitable for crankshafts with ultra-smooth surfaces that can operate under thin oil conditions. This polymer coating material is highly adaptable and therefore provides excellent engine running-in characteristics. Both polymer coatings reduce friction and improve wear resistance compared to aluminum (also in the field of heavy-duty vehicles). Compared to IROX, IROX® 2 further enhances anti-seizure and anti-fatigue properties. As a result, Federal-Mogul Powertrain offers an optimized design tailored to the customer's specific application.

“The two coatings, IROX and IROX® 2, are suitable for aluminum and copper-based bearing materials for light and heavy-duty vehicle engines,” said Stefan Rittmann, Technical Director, Bearing Engineering, Federal-Mount Powertrain. “They are hybrid and Particularly effective in stop applications, these applications place higher demands on the bearing bush during frequent restarts. The coating is a PAI (polyamideimide) polymer resin binder containing dispersed throughout the matrix. A large number of additives. The development of IROX® 2 requires molecular modification of the binder and minor changes to the composition. For example, IROX® 2 does not contain silicon carbide particles and has a higher solids content than IROX. a synergistic mixture of lubricants."

At the Hannover 2018 IAA Commercial Vehicles Exhibition (Hall 13, Booth C30), held from September 19 to September 27, the Federal-Mogul Powertrain will showcase the new IROX® 2 high-performance polymer for heavy-duty vehicle applications. Coated bearing pads and many other products.
