Abstract

Iron oxide functions as a wear- and cavitation-inhibiting additive in the plastic sliding layer(s) of composite bearings for oil-lubricated applications. The sliding layers predominantly consist of thermoplastic fluoropolymers. The addition of iron oxide to PTFE-based materials reduces the destruction of the sliding surface owing to the appearance of cavitation if the materials are used in the presence of oil.
