Abstract

L'invention concerne un procédé de fabrication d'une composition de traitement. Un cation de lithium et du dioxyde de carbone sont combinés dans un milieu aqueux pour former la composition de traitement comprenant du carbonate de lithium in situ. L'invention concerne également un système et un procédé permettant de maintenir un bain de traitement formé à partir d'une composition de traitement comprenant du carbonate de lithium. Du dioxyde de carbone et/ou un sel de lithium sont introduits dans le bain en une quantité suffisante pour maintenir le pH du bain de traitement sur une plage de 9,5 à 12,5, la quantité de lithium sur une plage de 5 ppm à 5500 ppm (calculée en tant que cation de lithium) et la quantité de carbonate sur une plage de 15 ppm à 25 000 ppm (calculée en tant que carbonate), sur la base du poids total du bain de traitement. L'invention concerne également des substrats traités avec la composition, un système et un procédé.
