Abstract
Corrosion inhibitor mixes comprising multiple salts. One mix includes zinc citrate, zinc oxalate and magnesium phosphate. A second mix includes the same two zinc salts, nickel oxalate and nickel phosphate. Either mix may be added to a film-forming binder such as a polymer suitable for a paint or primer, to inhibit corrosion, especially when used with a metallic substrate. The resulting product of the inhibitor mix and binder is especially useful in inhibiting corrosion when applied to an aircraft surface.
Claims29
A corrosion inhibitor composition comprising at least two metal polycarboxylate salts and at least one non-lithium metallic phosphate salt.
A corrosion protection coating for a metallic surface, comprising:
- a binder;
- and
- a corrosion inhibitor mix comprising zinc oxalate, zinc citrate, and magnesium phosphate.
A method of protecting an aluminum alloy comprising at least part of a surface of an aircraft, the method comprising:
- coating the surface with a corrosion protection coating comprising a binder, a corrosion inhibitor mix, and coated aluminum alloy particles that are more anodic than the aluminum alloy surface;
- wherein the corrosion inhibitor mix consists essentially of zinc oxalate 25-75% by weight of inhibitor mix, zinc citrate 25-75%, and magnesium phosphate 5-30%.
A method of making a corrosion inhibiting product, the method comprising:
- mixing a corrosion inhibitor mix with a binder, the corrosion inhibitor mix comprising zinc oxalate 25-75% by weight of inhibitor mix, zinc citrate 25-75%, and magnesium phosphate 5-30%;
- wherein the binder is selected to form a paint, a primer, a grease, an oil, a gel, a wax, an elastomer, a sealant or a gasket.
A corrosion protection coating for a metallic surface, comprising:
- a binder;
- and
- a corrosion inhibitor mix comprising zinc oxalate, zinc citrate, nickel oxalate and nickel phosphate.
A method of protecting an aluminum alloy comprising at least part of a surface of an aircraft, the method comprising:
