Corrosion inhibition properties of nanobis[3-(trimethoxysilyl)propyl]amine on corrosion of borosilicate 7740 Pyrex glass in a solution of synthesized HBF4 was analyzed through gravimetric, galvanostatic discharge, polarization Tafel, and EIS techniques. The results revealed that the degree of inhibitory effect rose with concentration. Further, kinetic and thermodynamic effects of temperature on corrosion rate were studied. Polarization and adsorption isotherm studies revealed that nanobis[3-(trimethoxysilyl)propyl]amine is a good anodic-type inhibitor. It was found that the adsorption isotherm can be described by the Langmuir model. Furthermore, microscopic surface analyses such as AFM, SEM, and EDX were used to characterize the surface morphology of borosilicate glass specimens.

纳米双[3-(三甲氧基甲硅烷基)丙基]胺对Pb / HBF 4 / PbO 2备用电池中玻璃安瓿的酸腐蚀抑制

纳米双[3-(三甲氧基甲硅烷基)丙基]胺对硼硅酸盐7740派热克斯玻璃在合成的HBF 4溶液中的腐蚀抑制性能通过重量分析,恒电流放电,极化塔菲尔分析和EIS技术进行了分析。结果表明,抑制作用的程度随浓度的增加而增加。此外,研究了温度对腐蚀速率的动力学和热力学影响。极化和吸附等温线研究表明,纳米双[3-(三甲氧基甲硅烷基)丙基]胺是一种良好的阳极型抑制剂。发现吸附等温线可以用Langmuir模型描述。此外,显微表面分析(例如AFM,SEM和EDX)用于表征硼硅酸盐玻璃样品的表面形态。
