Abstract Effect of three kinds of ion bombardments,including deposited with d.c.bias voltages,circulated-argon ion bombardment,and at in tervals on microstructures and corrosion resistance of aluminum coatings on uranium substrate was investigated.The results show that coating microstructu res are influenced strongly by ion bombardment methods,of which coating microstr uctures correspond to their different corrosion resistance to uranium. The microstructures are much more closely packed and the corrosion resistance ar e much better at -100 V,-200 V and -500 V than those of at -300 V,0 V .The microstructures and corrosion resistance of aluminum coatings ca n also be improved remarkably by both circulated-argon ion bombardment and at in tervals deposition.All of aluminum coatings can provide protection for uranium t o different extent.
