Corrosion/Electrochemistry of Monocrystalline and Polycrystalline Beryllium in Aqueous Chloride Environment

PDF Version Also Available for Download.

Description

Corrosion characteristics of high-purity polycrystalline beryllium as a function of pH and NaCl concentration were studied at 25 C, using cyclic polarization tests. Single crystal beryllium specimens oriented close to the (0001), (1010), and (1120) planes using Laue back reflection techniques were studied using cyclic polarization tests in 0.01M NaCl with a nominal pH of 7. Pit morphology of the polycrystalline and single crystals was studied using conventional scanning electron microscopy. On the polycrystalline specimens, passivity appears to be more a function of solution pH than of chloride concentration. Single crystal studies show dramatic differences in cyclic polarization plots and ... continued below

Description

Corrosion characteristics of high-purity polycrystalline beryllium as a function of pH and NaCl concentration were studied at 25 C, using cyclic polarization tests. Single crystal beryllium specimens oriented close to the (0001), (1010), and (1120) planes using Laue back reflection techniques were studied using cyclic polarization tests in 0.01M NaCl with a nominal pH of 7. Pit morphology of the polycrystalline and single crystals was studied using conventional scanning electron microscopy. On the polycrystalline specimens, passivity appears to be more a function of solution pH than of chloride concentration. Single crystal studies show dramatic differences in cyclic polarization plots and SEM micrographs. The two prism planes (1010) and (1120) behave similarly while the basal plane (0001) behaved in a substantially different manner.
