摘要：

A number of different coatings (aluminum, zinc, magnesium, Al-Zn, Al-Mg, nickel, titanium, TiN and aluminum on TiN) were applied by the arc plasma physical vapor deposition technique to a depleted uranium (DU) alloy for corrosion protection assessment. The as-deposited specimens were examined by scanning electron microscopy for surface morphology and tested for adhesion. Electrochemical polarization tests and immersion tests were conducted in aerated 3.5 wt.% NaCl solution. The results of the electrochemical polarization scans and observations after long-term exposure tests indicated that the two alloys Al-Zn and Al-Mg appear to be the best sacrificial coating materials for improving the corrosion resistance of DU-0.75Ti.
