Assessment of corrosion-resistant coatings for a depleted U-0. 75 Ti alloy. Technical report
Technical Report
·
OSTI ID:6068408
Aluminum, zinc, magnesium, Al-Zn, Al-Mg, nickel, titanium, TiN and Al/TiN coatings were applied by the arc plasma physical vapor deposition (PVD) technique to a depleted uranium (DU) alloy for corrosion protection assessment. The as-deposited specimens were examined by scanning electron microscopy (SEM) for surface morphology and tested for adhesion. Electrochemical polarization tests and immersion tests were conducted in aerated 3.5 wt.% NaCl solution. Results of electrochemical polarization scans and observations after long-term exposure tests indicated that both Al-Zn and Al-Mg alloys appear to be the best sacrificial coating materials for improving the corrosion resistance of DU-0.75 Ti.
