Abstract:
A lubricant composition includes a base oil and one or more alkylethercarboxylic acid corrosion inhibitor(s) having the formula (I) : In this formula, R is a straight or branched chain C6-C18 alkyl group and n is a number of from 0 to 5. The lubricant composition can be utilized in a method for reducing corrosion of a steel article. The method includes the steps of providing the base oil and providing the one or more alkylethercarboxylic acid corrosion inhibitor(s). The method also includes the step of combining the base oil and the one or more alkylethercarboxylic acid corrosion inhibitor(s) to form the lubricant composition including less than about 0.1 weight percent of the one or more alkylethercarboxylic acid corrosion inhibitor(s). The method further includes the step of applying the lubricant composition to the steel article wherein the steel article passes corrosion testing according to ASTM D 665 B.
