Corrosion mechanisms of Zr-based bulk metallic glasses in NaBr solution
Source abstract
Abstract
In this paper, the corrosion mechanisms of Zr 55Cu 35Al 10 and Zr 56Co 28Al 16 bulk metallic glasses (BMGs) in 3.5 wt.% NaBr solution was systematically investigated by the kinetic potential polarization and electrochemical impedance spectroscopy. Both Zr 55Cu 35Al 10 and Zr 56Co 28Al 16 BMGs were subjected to pitting damage during the polarization process in NaBr solution due to the presence of Br − ions. However, Zr 56Co 28Al 16 BMG exhibits better corrosion resistance compared to Zr 55Cu 35Al 10 BMG. Zr 55Cu 35Al 10 BMG experiences selective dissolution of alloying elements under the attack of Br −, and Cu element was enriched in the corrosion pit. The surface of Zr 56Co 28Al 16 BMG shows a more uniform distribution of elements after corrosion. Simultaneously, the substitution of Cu by Co changes the composition of the passive films and increases the relative content of ZrO 2, which is a principal factor contributing to the enhanced stability of Zr 56Co 28Al 16 BMG`s passive film.
