Nano-Scale Wear Testing
Application Note
Introduction
The most common materials for bearing fabrication are metals, such as low-carbon steel, stainless
steel, chrome steel and high-speed steel. Polymeric materials are alternative candidates due to
their self-lubrication ability, high impact durability, high corrosion resistance, low specific gravity,
and high melting temperature. Polymers have therefore received widespread attention as new
tribological materials for dry, aqueous and corrosive conditions. Among these polymeric materials,
polytetrafluoroethylene (PTFE), polyether ether ketone (PEEK) and also their composites are often used
in tribological applications.
In fans used for cooling of computers and other electronics, it has been found that one of the main
contributors to failure is degradation of the miniature ball bearings [1], with det |
