OVERCORROSION ON THE SURFACE OF 6063 ALUMINIUM EXTRUSION
6063铝型材表面过腐蚀的研究

By means of MET,SEM and EPMA,overcorrosion morphology on the surface of 6063 aluminum extrusion,which often appears during the caustic washing process of pretreatment of anodizing,was observed ,and corrosion products were examined. Overcorrosion mechanism
