Abstract High performance polymeric materials such as poly-ether-ether-ketone (PEEK) are increasingly being used for challenging tribological applications in order to replace metal parts in vehicle engines and transmissions. The tribology of natural PEEK. under oil-lubricated conditions. was studied for different metal counterbody finishes. https://www.spidertattooz.com/2ft-LED-Strip-Light-Fixture-10-19-Watts-3000-Lumens-35K-40K-50K-120-277V/
