摘要：

An environmental friendly corrosion inhibitor was prepared from polyaspartic acid, zinc sulphate, hexadecylldimethyl (2-sulphite) ethyl ammonium and hydroxyphosphonoacetic acid. The corrosion inhibition performance of the enviromentally friendly corrosion inhibitor on A3 carbon steel in seawater was studied by rotary hanging-piece corrosion tests and steady polarization. The corrosion testing pieces were characterized by scanning electron microscope. The result showed that the corrosion inhibition rate could reach 95 % when the concentration of the corrosion inhibitor was 100 mg L-1 at temperatures 40, 50 or 60 degrees C in seawater and the efficiency of biodegradability was 86.57 % in 28 days.
