| 摘 要： | The corrosion behavior of coatings of pure zinc and Zn-Al,Zn-Al-RE alloys in NaCl solu-tions was studied by salt-spray experiments,even corrosion experiments and electrochemical measurementsof bi-directional polarization curves and a.c.impedance in weak polarization region consistent regularitieswere obtained by these different methods,viz.,the corrosion resistance of Zn could be enhanced by alloying itwith Al,and particularly with Al-RE.The causes of enhancement of corrosion resistance by RE were alsodiscussed.
