METHOD FOR PARTICLE SURFACE TREATMENT OF A CERAMIC POWDER AND CERAMIC POWDER PARTICLES OBTAINED BY SAID METHOD

摘要

The invention concerns a method for surface treatment of a ceramic material in powder form, wherein said method comprising the step of providing a powder formed of a plurality of particles of the ceramic material to be treated, and wherein said ceramic powder particles are subjected to an ion implantation process by directing towards an external surface of said particles a beam of singly or multiply charged ions produced by a charge of singly or multiply charged ions, for example of the electron cyclotron resonance ECR type, wherein said particles have a generally polyhedral shape.;The invention also concerns a material in powder form, formed of a plurality of particles having a ceramic external layer and a ceramic core, wherein said particles have a generally polyhedral shape.
