Electrically Conductive Solid Powder Lubrication
|Applications using electromagnetic induction such as railguns, motors, and generators, have always suffered from a lack of viable lubrication at the mating interfaces responsible for transferring current. Such a lubricant must maintain or enhance the contact resistance of the bare surfaces while reducing both friction and wear. In this project, the potential for electrically conductive powder lubricants is explored by combining copper powder with known powder lubricants.
