Beschreibung
Zusammenfassung:	Disclosed herein is a method for treating an article made of self-passivating metal including applying reagent to a surface portion of the article and applying laser light to the surface portion of the article to chemically activate the reagent, wherein the chemical activating of the reagent treats the surface portion for modification of one or more properties. L'invention concerne un procédé pour traiter un article constitué d'un métal à auto-passivation qui consiste à appliquer un réactif sur une partie de surface de l'article et à appliquer une lumière laser sur la partie de surface de l'article pour activer chimiquement le réactif ; l'activation chimique du réactif traitant la partie de surface pour la modification d'une ou plusieurs propriétés.
