BORATED AND NON BORATED OVERBASED CARBOXYLATES AS CORROSION INHIBITORS ABSTRACT OF THE DISCLOSURE A corrosion inhibitor additive for gear oil formu- lations is disclosed in the form of an overbased carboxylate which can be in a borated or non-borated form. Borated versions of the overbased carboxylate are preferred and are obtained by reacting a boron reactant such as boric acid with an overbased carboxylate. The overbased carboxylate in its borated and non-borated forms has been found to be effective in improving the corrosion inhibiting properties of gear oil formulations which are used under severe operating conditions wherein the gear oil might come into contact with contaminant water. A method of improving the corrosion resistance of a gear oil having contaminant water therein is also disclosed.
