摘　　要：采用失重法研究了含钨杂多酸在ＮａＣｌ 溶液中对钢铁腐蚀行为的影响．实验结果表明所研究的杂多化合物对钢铁均具有一定的缓蚀作用．但杂多酸盐特别是缺位型杂多酸盐的缓蚀效果较好．The influences of heteropoly compounds containing tungsten on corrosion behaviour of mild steel in sodium chloride solution were investigated by weight loss measurements. The results showed that all the heteropoly compounds under study more or less inhibited the corrosion of steel, but heteropoly salts especially lacunary salts had significant corrosion resistance to the steel.

关 键 词：杂多化合物 缓蚀剂 缓蚀效率
