Abstract
An corrosion inhibitor was prepared from polyaspartic acid(PASP),sodium gluconate,zinc sulfate and hydroxyphosphonoacetic acid(HPAA).The performance of corrosion inhibition was evaluated by rotary hanging-piece corrosion tests and steady polarization.The result showed that the corrosion inhibitor was an anodic inhibitor and had good corrosion inhibition performance in seawater.The corrosion inhibition rates were above 94% when the concentration of corrosion inhibitor was 100mg/L in seawater.
