摘要：

The adhesion, soundness and comparative quality of various coatings on a depleted uranium (DU-0.75Ti) alloy were evaluated with a CSEM Revetest automatic scratch tester. These coatings, namely aluminum, magnesium, zinc, titanium, Al-Zn, Al-Mg, TiN and Al/TiN, were deposited by a cathodic arc plasma physical vapor deposition process. During scratch testing the acoustic emission signal intensity, the frictional force and the friction coefficient were plotted vs. load. Scratch test results were correlated with coating microstructure characteristics as determined by optical and scanning electron microscopy. Al-Zn and Al-Mg coatings exhibit higher cohesive and adhesive (critical) loads and appear to be the best sacrificial coating materials for DU-0.75Ti.
