The Performance of Perfluoropolyalkyethers Under Boundary Conditions
Abstract
Perfluoropolyalkylethers (PFPEs) are a relatively recent addition to the family of lubricants used in spacecraft applications. They have excellent properties but do not perform well under boundary lubrication conditions. This has been demonstrated in testing under continuous rolling and oscillatory motion. The PFPEs degrade under conditions in which reactive iron metal is exposed, leading to catalytic reactions. Improved performance can also be achieved through the prevention of metallic iron exposure by using ceramic hard- coated and solid ball-bearing components.
