Abstract

The present invention relates to a method for treating a mechanical part (2, 3) comprising a functional surface (8) that is made of NiP and is intended to come into frictional contact with another functional surface, the method comprising a step of oxidising and/or phosphating the functional surface so as to artificially form an oxide layer (9) and/or a phosphate layer (10), respectively, on the functional surface (8), the phosphate layer (10) being a layer of Ni or Zn phosphates.
