Compositions and methods for inhibiting corrosion of metallic surfaces in contact with an aqueous medium such as copper, copper alloy, and steel surfaces of an open recirculating cooling water system. In certain embodiments, an aromatic triazole having an anionic substituent bonded to a nitrogen atom of the triazole (ANST) is used as the corrosion inhibitor. In other embodiments, the corrosion inhibitor is a reaction product of an aromatic triazole and an aldehyde (ATA).

Provided herein are methods and compositions for chemical mechanical polishing (CMP) of metals. The present methods and compositions involve the use of a corrosion inhibitor having the general formula C.sub.mH.sub.2m+1(OCH.sub.2CH.sub.2).sub.n-L-R in the CMP slurry composition, where m is an integer between 6 and 11, inclusive of end points, and n is an integer greater than or equal to 6, L is a bond, O, S, R.sup.1, SR.sup.1, or OR.sup.1, where R.sup.1 is a C.sub.1-4 alkylene; and R is an anionic group. The present methods and compositions can be used to achieve a high metal removal rate, while effectively inhibiting metal corrosion during CMP, and are particularly useful for CMP of cobalt (Co).
