摘要
A method of enhancing corrosion inhibition of inorganic corrosion inhibitors, particularly stabilized phosphate corrosion inhibitors, when used in high hardness waters containing at least 800 ppm total hardness which comprises adding to the high hardness waters a combined product which includes both the inorganic corrosion inhibitor system and an effective amount of a water-soluble acrylic acid:acrylamide copolymer having an acrylic acid:acrylamide weight ratio between 1:4 and 1:2 and having a molecular weight between 1,000-25,000.
