Lubrication

Lubrication, perhaps, is the most commonly used technique to avoid machinery wear. In the
ideal lubrication condition, the lubricant film is thick enough to separate completely the sliding
surfaces. Even when complete separation is not possible, lubrication can reduce wear by
making adhesion more difficult, for example. This is how extreme pressure oil works. Sulfur and
phosphor are common EP additives; they make steel adhesion more difficult. It is no surprise
that high-quality weldable steels have only a very small amount of these two elements.

There are also problems that can attack lubricants, consider the following causes of
chemical damage and the potential for their control or intervention by maintenance
practices:

 Lubricants with ineffective or distressed barrier-film corrosion inhibitors
 Lubricants prone to rapid oxidation (acid producing)
 Crankcase lubricants with impaired alkalinity reserve (acid neutralizing)
 Overextended oil change intervals
 Oil contamination by water and/or acids from the work environment
 Uncontrolled growth of biological contamination
 Moist headspace of tanks, sumps and other lubrication compartments
 Exceedingly high operating temperatures
 Improper use of chemically aggressive antiscuff (EP, etc.) additivies
 Improper preservation of stored or laid-up equipment; protection from moisture and
corrosion agents
 Lubricants that are incompatible with seals, process chemicals, machine metallurgy
or surface treatments
