摘要
采用电化学方法研究了LaFe10.8Co0.7Si1.5C0.2磁制冷材料在水介质中添加不同缓蚀剂后的腐蚀行为。结果表明,不同种类的无机缓蚀剂均对LaFe10.8Co0.7Si1.5C0.2合金有缓蚀作用。在酸性条件下(pH=6.5),K2CrO7和Na2CO3复配时的缓蚀效果最好,缓蚀效率为90.00%;在碱性条件下(pH=8.0),Na2MoO4·2H2O和Na2HPO4·12H2O复配时的缓蚀效果最好,缓蚀效率为82.57%。
Effects of different corrosion inhibitors on corrosion behavior of LaFe10.8Co0.7Si1.5C0.2 in aqueous media were investigated by electrochemical techniques. The results show that all studied inhibitors have inhibition effect on LaFe10.8Co0.7Si1.5C0.2 The best inhibition efficiency under acid condition （pH= 6. 5） is 90. 00 % by the inhibitor made of K2CrO7 and Na2CO3, and 82. 57% by the inhibitor made of LaFe10.8Co0.7Si1.5C0.2 under alkaline condition （pH=8）.
