Abstract:
    Corrosion-inhibiting compositions are described which comprise a mixture of (A) at least one oil-soluble neutral or basic alkali metal or alkaline earth metal salt or complex of at least one organic acid, and (B) a nitrogen- and boron-containing composition which is the reaction product of at least one amino alcohol, at least one of a boric acid or boron trioxide, and at least one organic carboxylic acid. Such compositions exhibit improved corrosion-inhibiting properties, especially when included in preservative oil applications. The composition of the invention contains, in addition to the nitrogen- and boron-containing compositions, a mixture of calcium and barium salts of sulfonic acids. Oil compositions containing the above-described corrosion-inhibiting compositions also are described. The disclosure also describes methods for inhibiting the corrosion of metal surfaces and metal articles which have been coated in accordance with the method of the invention.
