采用电偶腐蚀方法和失重法筛选出适用于内燃机冷却系统的DJ－W复合缓蚀剂，其缓蚀率达到90％以上。采用扫描电镜（SEM）及俄歇电子能谱（AES）等表面分析技术，结合极化曲线测量，研究了铸铝、铸铁、焊锡在内燃机冷却系统中的腐蚀机理和DJ－W复合缓蚀剂的缓蚀机理。
The galvanic corrosion method and the weight loss method were used to select DJ-W composite corrosion inhibitors suitable for the internal combustion engine cooling system, and the corrosion inhibition rate reached more than 90%. The corrosion mechanism of cast aluminum, cast iron and solder in the cooling system of internal combustion engine and the corrosion mechanism of DJ-W composite corrosion inhibitor were studied by means of SEM and Auger electron spectroscopy (AES) The corrosion inhibition mechanism.
