Abstract
The effect of sodium benzoate (BS) additives on known copper corrosion inhibitors 1,2,3-benzotriazole (BTA) and sodium laurate (LS) in neutral chloride solutions is considered. It has been shown that the addition of BTA to these compounds increases the protective properties of BTA and LS on the MNZh-5-1 copper alloy. According to polarization measurements, there is a sharp shift in the potential of local depassivation in the case of combined use of BTA with BS at their equimolar ratio. According to the results of corrosion tests, both studied equimolar compositions with BS protect the copper alloy from corrosion in a 3% NaCl solution.
