Low friction / Lubricants / Reduce abrasive wear / Good running in

Coating some chemical on material to increase lubrication, reduce friction, increase wear resistance to prolong their service life span. Without lubrication, when the harder material moves onto softer material with friction, will results in scuffing, pouching, or wear on surface of softer material.

The damage will directly affect to working performance, especially with the part that receive constantly friction such as gear, bearing, shaft, etc.
