The DLC coatings are chemically inert, have low friction coefficient and good wear resistance.
To resist wear, biomedical components require coatings that are exceptionally hard, have low friction, and are bioinert.
The results showed that the texture surface with the high dimple density had low friction at low and high applied load under dry friction.
Copper graphite composites which have low friction coefficient can be used as bearing materials in lieu of materials containing lead which cause environmental problems.
Highly fluorinated plasma polymers are chemically inert, acid resistant and have low friction coefficients, thereby being useful in chemical laboratories and for tribological applications.
Cu P Cg SiC composite coatings showed a moderate roughness, hardness between Cu P SiC and Cu P Cg coatings, had low friction and good anti-wear properties.
US-based Bal Seal Engineering Inc has expanded its line of seal materials to include SP191 – a polyimide-filled polytetrafluoroethylene compound developed to provide sustained sealing in applications that involve high temperatures, but also have low friction requirements.
The study of friction behaviors of the CrN/Ag multilayers against 100Cr6 steel balls reveals that the multilayers have low friction coefficients in comparison with that of a CrN single layer.
Nanocomposite Ti Ni C coatings, with nanosized carbide grains in an amorphous carbon (a-C) matrix have been suggested to have low friction and low contact resistance making them suitable for sliding electrical contacts.
