← ScienceWhich destructive outcome occurs due to thin-film lubricant breakdown?
A)Increased friction and adhesive wear✓
B)Reduced hydrodynamic lubrication thickness
C)Enhanced rolling contact fatigue life
D)Higher oxidation and corrosion resistance
💡 Explanation
When the lubricant film thins unevenly, spectral reflectance interference causes variations in thickness which leads to localized dry contact areas causing increased friction and adhesive wear; therefore this occurs rather than reduced fatigue because the mechanism preventing contact is now lost.
