Definitions

  • sliding contact pieces are in particular carbon brushes, e.g. for starters, as well as grinding pieces, e.g. for pantographs.
  • a first possibility is characterized in that the admixture is coated in such a way that it does not form any alloy with the copper.
  • the primary consideration here is to coat the admixture before it is introduced into the mold for producing the sliding contact piece.
  • the admixture is introduced into a binder in such a way that it does not form any alloy with the copper.
  • the binder can also be carbon (graphite), possibly with other binder additives. It is also important here that the admixture is covered by the binder.
