Abstract. Chemosorbic compounds with metal occur 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 interfacial shear force at local contacts. FOM coatings show good elasticity in rough contacts, but at 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
