Investigation of the Phenomenon of Selective Migration in Friction (Issledovanie Yavleniya Izbiratel nogo Perenosa pri Trenii)
A review is given of the way in which selective migration reduces wear. The process involves a series of stages; selective diffusion of atoms from the surface of an alloy, e.g. Sn or Zn from copper alloys, weakening of the surface layer, the formation of an electrostatic field in which metal ions an...

| Zusammenfassung: | A review is given of the way in which selective migration reduces wear. The process involves a series of stages; selective diffusion of atoms from the surface of an alloy, e.g. Sn or Zn from copper alloys, weakening of the surface layer, the formation of an electrostatic field in which metal ions and colloidal particles migrate, and the formation of a surface film from these particles. Specific fluid lubricants, e.g. glycerine, play an important role by inhibiting the formation of oxide films and by providing a medium for particle migration. (Author)
