摘要
Hydroxamic acid containing low molecular weight polymers have been found to be excellent corrosion inhibitors for iron and steel alloys in contact with industrial waters. When the waters contain hardness ions, such as calcium, magnesium, and mixtures thereof, the waters are preferably treated with combinations of the hydroxamic acid containing polymers and scale inhibiting/dispersing polymers, which polymers do not contain hydroxamic acid functional groups. The hydroxamic acid containing polymers, as well as the combination of hydroxamic acid and scale inhibiting/dispersing polymers may also both be formulated with other corrosion inhibitors.
