Oil Free Machinery and “Zero Wear”- Dream or Reality?

Abstract

Original equipment manufacturers (OEMs) and end-users perceive “Zero Wear” differently. The “Zero Wear” approach will be put into a general relation for different applications and illuminated by individual paths, either based on monolithic materials, thin film coatings or alternative base oils, featuring triboactive materials and lubricious oxides for tribological engine components and dry running foil bearings or specific DLC, ta-C and novel Zirconium-based thin film coatings for concentrated contacts above FZG 14 and alternative engine oils (NoSAP & bio-no-tox). The associated tribometric test equipments for these examples will also be detailed.
