New Concept of the Performance of Copper/ Copper Alloy Nanopowders introduced in Rubbing Contacts

摘要

The performance of copper alloy nanopowder lubricants introduced in rubbing contacts was studied. It was determined that under friction the alloy lattice destruction occurs and formation of intermetallic compounds and its further decomposition with active copper liberation take place. Its amount depends on the chemistry of nanocrystalline alloys and their crystal lattice strength.
