Use of a Composition for Inhibition of Corrosion of Metals or Metal Alloys and Method for Inhibition of Corrosion of Metals or Metal Alloys

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a corrosion inhibition composition and method for protecting metals and metal alloys from corrosion. The composition is environmentally friendly and contains at least one zinc carboxylate (such as zinc gluconate, citrate, acetate, etc.) and calcium gluconate in defined ratios. Optionally, it may also include magnesium carboxylate and chelating agents. The invention allows the protection of a wide range of metals and their alloys (e.g., iron, aluminum, copper, steel, zinc, magnesium) in both aqueous and mixed solvent systems, offering high corrosion inhibition efficiency over extended periods.

Use CasesContent extracted from patent full text and abstract with AI.

• Addition to hydraulic fluids to prevent corrosion of internal components.
• Incorporation into household and industrial cleaners to protect machine and appliance parts.
• Formulation into dishwashing detergents (tablets, powders, liquids) to mitigate utensil and machine corrosion.
• Inclusion in paints or coatings for corrosion-resistant finishes on metal surfaces.
• Use in deicing fluids for roads, airport runways, and aircraft, to reduce corrosion of exposed metal parts.
• Addition to lubricants and metal working fluids to protect metal surfaces during processing.
• Use in automotive coolants to protect radiators and engine components.
• Addition to solar fluids, heating systems, or coolant fluids for supermarkets and containers to extend the lifespan of metal parts.
• Use in off-shore drilling fluids, heat transfer fluids, and temporary protection for storage or transit of metal goods.
• Applications in the production and processing of cast iron, aluminum, magnesium, and copper.

BenefitsContent extracted from patent full text and abstract with AI.

• Environmentally friendly—composed of biodegradable, non-toxic, and generally recognized as safe (GRAS) substances.
• Broad-spectrum corrosion inhibition efficiency—protects a wide variety of metals and alloys (iron, steel, aluminum, copper, zinc, magnesium, etc.) in one composition.
• Effective in both aqueous and mixed (water/organic solvent) systems and remains functional over a wide concentration range.
• Reduces need for hazardous, toxic, or environmentally problematic corrosion inhibitors found in traditional systems.
• Prevents ionization and degradation of metals in various industrial, commercial, and domestic settings, increasing equipment/material lifespan.
• Compatible with other additives and forms (solid or liquid), and does not require complex preparation before application.
• Long-lasting protection—even after extended exposure times (up to 8 weeks), high inhibition efficiency is maintained.
• Complies with environmental regulations and sustainability initiatives, such as the European Green Deal.
