The invention relates to a method for the surface treatment of a fluid product dispensing device. The method comprises a step in which at least one surface to be treated of at least one part of the device is subjected to ion implantation modification using multi-energy and multi-charged ion beams, said modified surface to be treated having anti-friction properties. The multi-charged ions are selected from among helium (He), nitrogen (N), oxygen (O), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the ion implantation is performed at a depth of between 0 and 3 µm. |
