WebLow-friction additives such as PTFE, oil, carbon fiber, and graphite powder can also significantly improve the wear performance of these polymers under certain conditions. It’s important to recognize that wear is a complex behavior that may include adhesion, abrasion, erosion and/or fatigue. WebTo reduce friction, oil is added to the engine. The oil coats the surfaces of the moving parts and makes them slippery. They slide over each other more easily, so there is less friction. Friction is always parallel to the surface in contact. In some cases, friction is desirable while in other cases, friction reduces the effectiveness of machines.
