通过烧杯试验和循环水系统，评估水质参数，尤其是朗格利尔指数（SI）对镀锌钢腐蚀的影响。由于有时发现含正SI的水至少与含负SI的水具有同样的腐蚀性，尤其是如果忽略溶解氧的影响，腐蚀速率与SI之间无法建立明确的关系。在佛罗里达州盖恩斯维尔的自来水和去离子水中，观察到在pH值为5-6.5的范围内腐蚀最快。总体结果表明，在腐蚀控制的实践中，硅仅应谨慎使用，并且预测水的腐蚀性也应考虑其他水质参数的影响。包括26个参考文献、表格和图表。

Jar tests and a circulating water system were used to evaluate the effect of water quality parameters, in particular the Langelier index (SI), on the corrosion of galvanized steel. Since waters with a positive SI were sometimes found to be at least as corrosive as waters with a negative SI, especially if the effect of dissolved oxygen was neglected, no definite relationship could be established between corrosion rate and SI. In both Gainesville, Florida, tap water and deionized water, corrosion was observed to be fastest in the pH range 5-6.5. Overall results suggest that the SI should be used only with caution in the practice of corrosion control and that prediction of a water's corrosivity should also consider the influence of other water quality parameters.
