摘要
海水中纯金属的电化学电位,是海洋环境中金属腐蚀和保护研究的一个最基本的物理-化学量。它不仅在腐蚀理论上,是确定某一腐蚀体系的阳极或阴极、估计在某一金属结构物上不同金属的配伍性等等的依据;而且在防腐技术上,是电化学防腐中选择阳极材料,金属-涂料保护层等等研究上都必不可少的一个基本参数。
A new application of the Φ(z/l, x) rule of chemical processes in seawater to electrochemical potential of metals in the same medium has been studied.According to the Φ(z/l, x) rule, we suggest a classification of electrochemical potentials Of metals in seawater and a quantitative calculation formula. The calculated results and. the experimental data are in good agreement.On the basis of the Born-Haber thermochemical cycle is the equation for quantitative calculation by this rule deduced.
