A Review of Transfer Films and Their Role in Ultra-Low-Wear Sliding of Polymers [PDF]
Lubricants, 2016 In dry sliding conditions, polytetrafluoroethylene (PTFE) composites can form thin, uniform, and protective transfer films on hard, metallic counterfaces that may play a significant role in friction and wear control. Qualitative characterizations of transfer film morphology, composition, and adhesion to the counterface suggest they are all good ...

A novel method for isolation and recovery of ceramic nanoparticles and metal wear debris from serum lubricants at ultra-low wear rates [PDF]
Acta Biomaterialia, 2016 Ceramics have been used to deliver significant improvements in the wear properties of orthopaedic bearing materials, which has made it challenging to isolate wear debris from simulator lubricants. Ceramics such as silicon nitride, as well as ceramic-like surface coatings on metal substrates have been explored as potential alternatives to conventional ...

Creation of ultra-low friction and wear surfaces for micro-devices using carbon films [PDF]
Wear, 2005 Abstract A great many of the micro-mechanical devices employ sliding contact between moving parts. Such devices include, for example, micro-engines, micro-motors, and near-contact or contact recording hard magnetic disk drives. In these devices, the tribological phenomena (friction, wear and stiction) largely determine device efficiency and ...

A low friction and ultra low wear rate PEEK/PTFE composite
Wear, 2006 This paper presents a PEEK filled PTFE composite that exhibits low friction and ultra-low wear. It is hypothesized that a synergistic effect shuts down the dominant wear mechanism of each constituent. The friction coefficient and wear rate of this composite material on lapped stainless steel were evaluated for samples with PEEK wt.% of 0, 5, 10, 20, 30,

In-situ formation of an ultra-low wear boundary tribofilm from carboxylic acid molecules
, 2022 Abstract This paper describes series of four-ball tribological and atomic force squeezing test results obtained under different contact pressures and sliding speeds (or squeezing speeds) and performed with poly-alpha-olefin suspended 0.5% weight percentage of different types of carboxylic acids.
