摘　　要：研制了一种二氧化氯体系中的碳钢缓蚀剂。用静态失重法、电化学方法研究了A_3钢在质量分数为200×10^(-6)二氧化氯溶液中的电化学性能及加入缓蚀剂后对A3钢的缓蚀作用。几种研究方法结果一致表明:0.20g的GL与0.15mL的HEDP复配能使A_3钢腐蚀率降低,腐蚀程度从重度腐蚀减轻到轻度腐蚀。此复配缓蚀剂的研究,对于碳钢在二氧化氯体系中的应用具有实际价值。A carbon steel inhibitor in chlorine dioxide system was developed. The electrochemical properties of A3 steel in chlo- rine dioxide solution （with chlorine dioxide mass fraction of 200× 10^-6） and the inhibiting ability of inhibitor to the Aa steel were investigated by static weight-loss measurement and electrochemical methods. Results show that the combination of 0.20 g GL and 0.15 mL HEDP can reduce the corrosive rates of A3 steel, and corrosion degree is reduced from heavy corrosion to mildly corrosion. The research in inhibitor has actual value for A3 steel used in chloride dioxide system.
