Abstract. The chemosorbic compounds with metal are composing after coating the surface with fluor-oligomeric material (FOM). Hardness, indentation and friction behavior of FOM coat were investigated. Scratch adhesion and friction tests show that the fluor-oligomeric film decreases the solid body micro-hardness and modifies contact rheology by reducing the shearing force at the local contact. FOM coat shows good elasticity in rough contacts, but with a higher hardness it may be more suitable for abrasive applications, i.e. reduced plasticity in a given tribo-contact.
