Title (EN) INHIBITING FERROUS METAL CORROSION BY AQUEOUS AMMONIATE SOLUTIONS
(FR) INHIBITION DE LA CORROSION DE METAUX FERREUX PAR LES SOLUTIONS AQUEUSES D'AMMONIURES
Abstract:
(EN) Aqueous solutions of ammonium chloride and ammonia that contain a water-soluble impurity normally tending to engender corrosion of ferrous metal are rendered corrosion-resistant by dissolving therein a small corrosion-inhibiting amount (e.g., up to about 5000 ppm wt/wt) of a water-soluble salt or oxide of zinc, aluminum, arsenic, antimony or bismuth.
(FR) L'invention porte sur des solutions aqueuses de chlorure d'ammonium et d'ammoniac contenant des impuretés hydrosolubles qui tendent normalement à provoquer la corrosion des métaux ferreux, mais qui sont rendues non corrosives lorsqu'on y dissout une faible quantité (par exemple jusqu'à environ 5000 ppm (poids/poids) d'un sel hydrosoluble ou d'un oxyde, de zinc, d'aluminum, d'arsenic, d'antimoine ou de bismuth.
