摘要
测定了在 pH =2～ 1 6范围内 ,铝的腐蚀电位 pH图 ,对铝腐蚀电位 pH图中的各临界线上的反应进行了分析 ,得到了铝在水溶液中腐蚀的钝化pH值范围 ,并建立了在不同 pH值范围内 ,铝的腐蚀电位方程 ;还测定了在 pH =7时 ,纯水及人造海水中铝的腐蚀极化曲线·
The graph of the aluminium corrosive electrical potential pH was gained by the measurement of different aluminum corrosive potential in the different pH water dissolution. The best passivation point of pH was determined by analyzing the reaction in every phrase boundary line in the graph. The polarization curves of aluminum in the pure water and the man made sea water are presented. It is shown the best passivation point of pH is 5 7 and aluminium is more corrodible when haloid ions exist.
