Abstract

The response surface methodology (RSM) was used to explore the experimental space, characterise the influence of deposition and drying conditions on corrosion resistance, and evaluate the interactions between these factors for zirconium conversion coatings on cold-rolled steel and zinc. A combination of non-electrochemical drop tests and electrochemical methods were utilised to evaluate corrosion resistance in a dilute Harrison's solution. The surface analysis confirmed the electrochemical results obtained under the conditions chosen by RSM. The uniform corrosion of both substrates guides the subsequent conversion process, while the best coating performance results from the interaction of pH, conversion time and bath concentration.
利用响应面方法表征钢和锌基材上锆转化涂层的沉积和保护性能
采用响应面方法 (RSM) 探索实验空间,确定沉积和干燥条件对耐腐蚀性的影响,并评估冷轧钢板和锌上锆转化涂层这些因素之间的相互作用。结合使用了非电化学滴落试验和电化学方法来评估稀 Harrison 溶液中的耐腐蚀性。表面分析证实了在 RSM 所选条件下获得的电化学结果。两种基材的均匀腐蚀为随后的转化过程提供了指导,而最佳涂层性能则是 pH 值、转化时间和浴液浓度相互作用的结果。
