Untersuchungen an Zylinderlaufbahnen mit neuer galvanisch aufgebrachter Eisenbeschichtung

Within the BMBF-program "Werkstoffinnovationen für Industrie und Gesellschaft - WING" pursued the cluster-project "NanoFerro - Motorblöcke für Hochlastanwendungen" the aim to apply a functional coating of nanocrystalline iron in cylinder liners of aluminum crankcases with an electrolytic deposition method as well as to analyze their functional properties. Key aspects were the development of optimal terms of deposition by pulse-plating as well as a substantial characterization of the electro-plated thin iron layer with regard to material scientific aspects. Furthermore tribological analyses were carried out in a ring/cylinder tribo-tester, in a single-cylinder engine and in a complete engine.
