COMPOSITIONS AND METHODS FOR INHIBITING CORROSION IN AQUEOUS MEDIA.

摘要

Methods and compositions are provided for corrosion inhibition treatment of aqueous systems such as cooling water systems The methods include conjoint use of a polivalent metal ion such as Al or Mn and a corrosion inhibitor/deposit control agent (DCA) to the water system. The corrosion inhibitor DCA agent may be an organic compound such as a hydroxyacid, phosphonocarboxylic acid, polyhydroxysuccinic acid, or polymaleic acid or anhydride.
