In order to treat the cams of a camshaft for an internal combustion vehicle, so as to reduce the friction coefficient thereof relative to a counterpart in an area provided with a hard coating made from amorphous Diamond-Like Carbon or DLC, the method involves disposing the cams on a support, bringing the support and the cams into a chamber placed under vacuum so as to clean said cams, bringing said support into relative movement along a trajectory of travel relative to a coating source, and taking said cams off the support before assembling them on a camshaft; the method involves disposing the cams on the support in a fixed configuration which, together with the trajectory, is defined in such a way that said cams are brought successively opposite the source with orientations and at distances substantially identical relative to said source, so as to deposit a hard coating made from amorphous Diamond-Like Carbon or DLC, selectively on the fraction of the section of the cams that is oriented towards the source. |
