Abstract
There is provided an electrical contact member where wear can be reduced. The electrical contact member is characterized by one or both of conductive metal particles and conductive metal fibers, at least outer circumferential surfaces of which have been modified with carbon nanofibers or carbon nanotubes, being disposed in a contact layer through which current flows.
Claims15
An electrical contact member, comprising:
- at least one from conductive metal particles and conductive metal fibers;
- and
- carbon nanofibers or carbon nanotubes embedded at least partially into the at least one from the conductive metal particles and the conductive metal fibers such that at least a portion of the carbon nanofibers or the carbon nanotubes protrudes from outer circumferential surfaces of the at least one from the conductive metal particles and the conductive metal fibers,
- wherein the at least one from the conductive metal particles and the conductive metal fibers having the embedded carbon nanofibers or the carbon nanotubes form a contact layer of the electrical contact member through which current flows.
