在室温条件下用液相直接沉淀法合成了6种Keggin结构的磷钨酸铵盐,并进行了IR光谱表征.采用静态、动态挂片失重法研究考察了6种多金属氧酸铵盐在水介质中对20~#钢的缓蚀作用,通过扫描电镜对金属表面成膜或腐蚀情况进行了分析和评价.研究结果表明,Keggin结构磷钨酸铵盐均是碳钢良好的缓蚀剂,有机铵盐的缓蚀性能优于无机铵盐.
在室溫條件下用液相直接沉澱法閤成瞭6種Keggin結構的燐鎢痠銨鹽,併進行瞭IR光譜錶徵.採用靜態、動態掛片失重法研究攷察瞭6種多金屬氧痠銨鹽在水介質中對20~#鋼的緩蝕作用,通過掃描電鏡對金屬錶麵成膜或腐蝕情況進行瞭分析和評價.研究結果錶明,Keggin結構燐鎢痠銨鹽均是碳鋼良好的緩蝕劑,有機銨鹽的緩蝕性能優于無機銨鹽.

Six kinds of ammonium heteropolytungstophosphates have been synthesized by direct precipitation in so-lution and characterized by IR. The corrosion inhibition of 20~# steel in aqueous media are investigated through static and dynamic weight-loss experiments. The filming pattern and corrosive state on the metal surface are analyzed by scanning electron microscope. The results show that the ammonium heteropolytungstophosphates with Keggin struc-tures are all excellent corrosion inhibitors on carbon steel, and the corrosion inhibition capacity of organic ammoni-um salt is better than their parent acid or inorganic ammonium salt.
