Average contact temperature and morphological details of the worn surface of copper based materials under high current density sliding against steel

Dry sliding of copper and sintered composites of composition Cu-bearing steel against AISI steel 1045 under electric current of high contact density have been carried out. It is shown that the surface layer of copper and composites undergoes structural changes and tribolayer containing iron, copper...

Description
Summary:Dry sliding of copper and sintered composites of composition Cu-bearing steel against AISI steel 1045 under electric current of high contact density have been carried out. It is shown that the surface layer of copper and composites undergoes structural changes and tribolayer containing iron, copper and FeO oxide is formed. It is noted that the thin contact layer contains about 40 at % of oxygen and 40 at % Fe. Appearance of signs of a liquid phase is morphological feature of worn surface. It is established that contact temperature does not exceed 300°C. It allows claiming that melting of metals in tribolayer does not happen.
