浅谈镀铁电解液对低温镀铁工艺的影响

Effect of Iron Plating Electrolyte on Low Temperature Iron Plating Process

本文详细介绍了镀铁电解液对低温镀铁工艺的影响,汇总了其基本类性和性能,目的在于解决当前工艺流程繁琐性、经济性等问题,总结注意事项以及电解液维护办法,解决镀层与基体结合强度差、镀层破裂或打卷现象、镀层粗糙存在针孔麻点、镀层出现层状结构等问题。本次研究采用实验分析法,对镀铁电解液配制进行优化调整,采用低碳钢和盐酸配制、氯化亚铁和盐酸直接配制的方式。试验结果显示,前者具有原材料取材方便、经济性高的优势,但溶解铁屑的时间较长;后者具有制备速度快、处理时间短的优势。

This paper provides a detailed introduction to the impact of iron plating electrolytes on low-temperature iron plating processes,summarizing their basic characteristics and performance.The aim is to solve the current process complexity,economy,and other issues,summarize precautions,and electrolyte maintenance methods,and solve problems such as poor bonding strength between the layer and substrate,cracking or curling of the coating,rough coating with pinhole pits,and layered structure of the coating.In this study,the preparation of iron plating electrolyte is optimized and adjusted by the experimental analysis method,using low-carbon steel and hydrochloric acid,and Iron(II)chloride and hydrochloric acid are directly prepared.The experimental results show that the former has the advantages of convenient raw material extraction and high economy,but it takes longer to dissolve iron filings;the latter has the advantages of fast preparation speed and short processing time.
