Abstract. The chemosorbic compounds with metal are composing after coating the surface with fluor-oligomeric material (FOM). Hardness, indentation and friction behaviour of FOM coat were investigated. Scratch adhesion and friction tests show that the fluor-oligomeric film decreases the micro-hardness of solid body and modifies the 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.

 

 

Keywords: fluor-oligomeric films, indentation, micro-hardness, chemosorbic compounds
