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.
