TiAlSiN coatings are deposited on zircaloy-4 by multi-arc ion plating at 50 A, 60 A and 70 A, respectively. The macro-morphology, micro-morphology, chemical composition and phases of the prepared coatings are observed and analyzed, and the high temperature oxidation behavior and adhesion strength of coatings are tested. The results demonstrate that the quantity of large particles on TiAlSiN coating increases gradually as the arc current increases, the coating becomes denser and denser with the porosity decreases gradually, and the content of Al elements in the coating increases gradually with ...
