用浸渍腐蚀试验,电化学极化测量和扫描电镜等方法研究了一种含磷、锌等活性元素的水溶性聚合物GP对铜和碳钢的腐蚀抑制作用。结果表明,GP在除氧的弱碱性溶液中对紫铜和A_3钢都具有较好的缓蚀性能,并对其缓蚀体理也作了初步探讨。
The corrosion inhibition of copper and carbon steel by water-soluble polymer GP containing phosphorus, zinc and other active elements GP was studied by immersion corrosion test, electrochemical polarization measurement and scanning electron microscopy. The results show that GP has a good corrosion inhibition performance on both copper and A 3 steel in deoxygenated weak alkaline solution, and its inhibition mechanism is also discussed.
