About wear of metal materials loaded by sliding friction and by electric current of high density

M.I. Aleutdinova, V.V. Fadin, A.V. Kolubaev


Unlubricated sliding of metals and steels has been realized under influence of electric current at contact density higher 100 A/cm2. It is shown that materials containing a lot of chemical elements or crystal phases in initial structure form light deteriorated layer of friction induced structures. This lead to low wear resistance of contact compared with contact of simple metals.
