Abstract

Procédé pour améliorer la réflectivité de particules, en vue de leur utilisation dans un procédé de fabrication additive, comprenant les étapes suivantes :- fourniture de particules en un alliage comprenant un premier élément et un deuxième élément,- mise en contact des particules avec une solution acide, la vitesse de gravure du premier élément dans la solution acide étant supérieure à la vitesse de gravure du deuxième élément, moyennant quoi on grave le premier élément et on structure à l’échelle nanométrique la surface des particules. Après l’étape de gravure, la réflectivité totale des particules à 1064nm est inférieure à 15%. L’alliage est, de préférence, un alliage aluminium-silicium tel que AlSi12, ou un alliage fer-silicium, tel que FeSi6. Figure pour l’abrégé : 2D
