Abstract
The inhibitory effect of a new derivative of the indazole family, namely, (Z)-2-(1-methyl-5-nitro-1H-indazol-4-yl)-3-(3-nitrophenyl) acrylonitrile (51K2) against corrosion of carbon steel in 1 M HCl medium at a temperature of 25°C has been evaluated by different techniques such as gravimetric methods, potential-intensity curves, and electrochemical impedance spectroscopy. The impact of the concentration on the inhibition efficiency was also studied. The results of weight loss measurements and electrochemical analyses obtained showed that the addition of 51K2 increases the inhibition efficiency by decreasing the corrosion rate, with a maximum inhibitory efficacy of 80%. In other words, 51K2 is a good anodic-type corrosion inhibitor of carbon steel in 1 M HCl.
采用重量法、电位强度曲线和电化学阻抗谱等方法，研究了一种新的茚唑族衍生物(Z)-2-(1-甲基-5-硝基- 1h -茚唑-4-基)-3-(3-硝基苯基)丙烯腈(51K2)在25℃下1 M HCl介质中对碳钢的腐蚀抑制作用。研究了浓度对抑菌效果的影响。失重测量和电化学分析结果表明，51K2的加入通过降低腐蚀速率来提高缓蚀效率，最大缓蚀率为80%。也就是说，51K2是碳钢在1 M HCl中良好的阳极型缓蚀剂。
