【摘要】 本文用量热法研究了Na₃PO₄,CuCl₂,吡啶对盐酸腐蚀铝速度的影响,发现Na₃PO₄和吡啶有缓蚀作用,而CuCl₂有增蚀作用,实验结果用吸附理论进行了解释,并推导出吡啶浓度与腐蚀速度之间的两个直线方程。更多还原

【Abstract】 The effect of Na₃PO₄, CuCl₂ and pyridine on corrosion rate of aluminium in hydrochloric acid solution has been studied by the thermometromic method.It is found that Na₃PO₄ and pyridine act as corrosion inhibition, while CuCl₂ act as corrosion accelaratlon. The experimetal results have been interpreted from absorption theory . Two linear equations between concentration of pyridine and corrosion rate have been deduced.更多还原
