EFFECT OF MOTOR OIL DEGRADATION AND METALLIC SURFACES‘ TREATMENT ON THEIR WETTABILITY

This work examined and showcases the change in wettability of motor oils in relation to their degradation and treatment of the surface they wet. Wettability is a complex scientific discipline which focuses on the interplay of a liquid placed upon a surface, their surrounding atmosphere, their „compatibility“, and their properties. Over 485 measurements were done, using the sessile drop method, to further showcase various aspects of wettability.
