摘要
通过调查研究发现某企业报废的铝搪瓷锅体表面条纹缺陷是由于铝材本身的冶金因素而非搪瓷化处理所导致。进一步地通过金相显微镜、扫描电镜技术对缺陷处铝材中的第二相粒子进行测试分析,并对铝搪瓷锅体新裸露铝表面阳极氧化处理后进行观察,排除了搪瓷条纹是由铝材中的粗大第二相粒子脱落所引起。综合以上检测分析,确定搪瓷条纹缺陷的产生是由于铝材中晶粒大小不均匀,导致拉深成型过程中铝材变形不协调,从而产生表面擦划伤,使得搪瓷化处理后表面出现条纹缺陷。
Through investigation and research,it was found that the surface stripe defects on the scrapped aluminum enamel pot body of a certain enterprise were caused by metallurgical factors of the aluminum material itself rather than enamel treatment.Further testing and analysis were conducted on the second phase particles in the defective aluminum material using metallographic microscopy and scanning electron microscopy techniques,and observation was conducted on the newly exposed aluminum surface of the aluminum enamel pot after anodizing treatment.It was ruled out that the enamel stripes were caused by the detachment of coarse second phase particles in the aluminum material.Based on the above inspection and analysis,it is determined that the occurrence of enamel stripe defects is due to uneven grain size in the aluminum material,which leads to inconsistent deformation of the aluminum material during deep drawing and forming,resulting in surface scratches and scratches,finally resulting in stripe defects on the surface after enamel treatment.
