NEW APPROACH IN OXIDATION
STABILITY TESTING OF THE GAS TURBINE OILS
OMV Refining & Marketing, Competence Center Lubes, 2320 Schwechat,
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.
