lubrication
Motor oil, a lubricant for automobile engines.
When machinery is idle, lubricants protect metal surfaces by acting as a preservative. The effectiveness of this protection is determined by two primary factors: the thickness of the lubricant film that remains on the metal surfaces and the specific chemical composition of the lubricant used. By maintaining a consistent coating, the lubricant serves as a barrier that prevents the exposure of metal to oxygen and moisture, which are the primary drivers of corrosion and the formation of rust.12
