ABSTRACT OF THE DISCLOSURE The invention relates to a method for the treatment of parts, the surfaces of which contain titanium. The part to be treated is disposed inside an enclosure. A vacuum is created in said enclosure until the pressure in the latter ranges from 1 to 10-8 Torr. An amount of oxygen ranging from 0.1 cmc to 60 cmc per cm2 of surface to be treated is introduced into the enclosure, and then the enclosure is heated to a temperature ranging from 450°C to 880°C. After this treatment the part is coated with a surface layer consisting essentially of titanium oxides and having a thickness greater than 15 microns to improve the frictional properties thereof.
