Abstract

The polyaspartic acid (PASP) composite was prepared from PASP , sodium gluconate , zinc sulfate , sodium tungstate and phosphate .The corrosion inhibition performance of PASP composite on A3 carbon steel in seawater was studied by using steady polarization. The results showed that PASP composite had good corrosion inhibition performance in seawater . When the concentration of PASP composite was 300 mg/L , the corrosion inhibition rate reached 79.25% .
