本文研究了电镀锌钢（EG）和磷化处理后塑性变形的形态和电化学特性。以前的研究集中在具有相同基底的线圈涂层的变形。成形对整个系统的影响是已知的，但对各个层的影响却不清楚。本文用扫描电镜分析了单轴和双轴变形后EG和PEG的表面变化，用交流阻抗谱和空间矢量电子技术分析了试样在0.1M NaCl溶液中的腐蚀情况。
This paper presents a morphological and electrochemical characterisation of electrogalvanised steel (EG) and phosphated electrogalvanised steel (PEG) after plastic deformation. Previous investigations focused on the deformation of a coil-coating with the same substrates. The effect of forming on the complete system is known but not its influence on the individual layers. The study now reported used SEM to analyse the surface changes of EG and PEG after uniaxial and biaxial deformation and EIS and SVET to characterise the corrosion of the samples when immersed in 0.1M NaCl.
