水淬高强钢板酸洗行为与缓蚀剂效果评价
Pickling Behavior of Water Quenched High Strength Steel Plates and Effect Evaluation of Corrosion Inhibitors
摘 要
水淬高强钢板的氧化皮极薄且分布不均,酸洗时必须采用适当的酸洗工艺和缓蚀剂以防止过酸洗并减少基材损失.通过正交试验研究温度、盐酸浓度和Fe2+浓度对DP590水淬高强钢板酸洗行为的影响,对国产A和进口B两种缓蚀剂的效果进行了评价.结果表明,温度对酸洗速率的影响最大,缓蚀剂A对基体具有较好的缓蚀效果.

Abstract
The oxide scale of water quenched high strength steel plates is extremely thin and inhomogeneous,thus a proper pickling process and corrosion inhibitor must be used to prevent the over-pickling and to decrease the loss of steel substrate.The effects of temperature,hydrochloric acid concentration and Fe2+ concentration on the pickling behavior of water quenched high strength steel plates were investigated by orthogonal tests,and the efficiency of two kinds of corrosion inhibitor A and B was evaluated.The results showed that temperature had the most obvious effect on the pickling rate,and the inhibitor A had a better effect to prevent the corrosion of substrate.
