Abstract: A method for surface treatment of a metal material in a powder state is provided, the method including obtaining a powder formed from a plurality of particles of the metal material to be treated; and subjecting the powder to an ion implantation process by directing a beam of singly-charged or multi-charged ions towards an outer surface of the particles, the beam being produced by a source of singly-charged or multi-charged ions, whereby the particles have an overall spherical shape with a radius (R). There is also provided a material in a powder state formed from a plurality of particles having a ceramic outer layer and a metal core, the particles having an overall spherical shape.

Abstract: A method for single or multiply charged ion implantation into a surface of a treated object, and a device for implementing the implantation method, the method including: directing towards the surface of the treated object an ion beam produced by an ion source of the electronic cyclotron resonance type; producing at least one primary electron beam and directing the primary electron beam so that it passes through the ion beam; and producing a secondary electron beam by reflecting the primary electron beam onto a target once the primary electron beam has traversed the ion beam, the target being oriented such that the secondary electron beam falls onto the surface of the treated object.
