摘　　要：四元海水缓蚀剂由聚天冬氨酸(PASP)、葡萄糖酸钠、七水硫酸锌与2-羟基膦酰基乙酸(HPAA)复配制得。利用失重法和电化学法研究了缓蚀剂在海水中对A3碳钢的缓蚀性能。结果表明,当缓蚀剂的用量为100 mg/L时,其缓蚀率大于94%,该缓蚀剂是一种抑制阳极腐蚀为主的缓蚀剂,在海水中具有优良的缓蚀性能。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.
