lubrications
Slickening fluid treatments
Lubrications are instances or applications of lubrication—the process of applying a substance to reduce friction between moving parts.
The word appears in technical contexts where multiple separate applications matter: The machine requires lubrications every eight hours of operation.
In practice, the singular lubrication is far more common.
