This study was undertaken to measure the electrochemical corrosion of amorphous Zr65Al8Ni15Cu12 (at.%) alloy ribbon under various conditions, including 0.4 mM HCl solution, and for various values of the pH and the immersion time. The corrosion potentials(Ecorr) for the amorphous Zr65Al8Ni15Cu12 alloy in 0.4 mM HCl decreased with increasing temperature; the corrosion current density(Icorr) increased with increasing temperature in general. The polarization resistance(Rp) was inversely proportional to the corrosion rate. While pH=7, 9, 11 was not as sensitive as pH=3, 5, pH=3 was more sensitive for amorphous Zr65Al8Ni15Cu12 alloy than other pHs specially. The change of mass in the 70 mM H2SO4 solution with immersion time was the greatest in the first 100 h.
