Abstract

Cette invention concerne l'ajout d'un inhibiteur de corrosion dopé au Boronium (produit synthétisé) obtenu à partir d'un produit de bore dans un système en tant qu'élément anti-corrosion pour les applications requises et pour accroître la résistance à la corrosion d'un métal (par exemple, le métal St37) en augmentant la quantité de concentration dans le système. Les caractéristiques les plus importantes du produit synthétisé tiennent au fait qu'il est dissous dans de l'eau et contient un élément de bore que l'on trouve en grande quantité dans notre pays. Un effet d'inhibition allant jusqu'à 90 % a été déterminé à une concentration molaire de 0,0025 du produit, qui est spécifiée en tant que concentration maximale. Dans ce contexte, le produit selon l'invention écarte les brevets de la littérature.
