AQUEOUS LIQUIDS CONTAINING METAL CAVITATION-EROSION CORROSION INHIBITORS

摘要

AQUEOUS LIQUIDS CONTAINING METAL CAVITATION-EROSION CORROSION INHIBITORS Compositions for inhibiting mineral scale and the corrosion of metals particularly the cavitation corrosion of aluminum in the presence of aqueous liquids are disclosed. The combination of a water-soluble phosphate with at least one of a water-soluble molybdate, tungstate, or selenate is disclosed as providing a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids.
