Title (EN) METHOD OF INHIBITING CORROSION OF FLUX-TREATED METAL SURFACES
(FR) PROCEDE D'INHIBITION DE LA CORROSION DE SURFACES METALLIQUES TRAITEES PAR FLUX
Abstract: front page image
(EN)This invention relates to a method of inhibiting the corrosion of flux-treated metal surfaces. The method comprises the step of contacting the flux-treated metal surface with a formulation comprising a corrosion inhibitor composition comprising one or more mono-carboxylic acids, or salts or isomers thereof, and an effective amount of a corrosion inhibiting surface active agent such as a water soluble alkali or alkaline earth metal nitrate salt. This method has been demonstrated to be a surprisingly effective means to inhibit corrosion of flux-treated metal surfaces found in the cooling systems of internal combustion engines.
(FR)Procédé d'inhibition de la corrosion de surfaces métalliques traitées par flux, qui consiste à mettre en contact lesdites surfaces métalliques avec une formulation contenant une composition inhibitrice de corrosion renfermant un ou plusieurs acides mono-carboxyliques ou sels ou isomères desdits acides, et une quantité efficace d'un agent tensioactif inhibiteur de corrosion tel qu'un sel de nitrate de métal alcalino-terreux ou alcalin hydrosoluble. Ledit procédé s'est révélé être un moyen étonnamment efficace d'inhiber la corrosion des surfaces métalliques traitées par flux que l'on trouve dans les systèmes de refroidissement des moteurs à combustion interne.
