一、前言铬酸盐是一种有效的氧化性缓蚀剂,然而,铬酸盐会污染环境。近些年来,钼酸盐和钨酸盐缓蚀剂的开发成功,引起了人们的极大兴趣。不过,目前开发的基本上是简单的钼酸钠和钨酸钠及应用范围不大的钨或钼的磷和硅杂多酸盐,并且其缓蚀效果常不如铬酸盐。本文报导由作者首次合成的钨铌酸钾在ZnSO_1等的协同作用下对碳钢的缓 I. Introduction Chromate is an effective oxidative corrosion inhibitor, however, chromates pollute the environment. In recent years, the successful development of molybdate and tungstate inhibitors has aroused great interest. However, what is currently being developed are basically simple sodium and sodium tungstates and phosphorus or heteropoly acid salts of tungsten or molybdenum with a limited range of applications, and their corrosion inhibition is often not as good as that of chromates. This paper reports the author for the first time the synthesis of potassium niobate ZnSO_1 synergistic effect on the slow carbon steel
