Abstract

Cr-based coatings with or without a Mo interlayer were deposited on a Zr substrate by multi-arc ion plating, and the effect of the Mo interlayer on the oxidation behavior of the coatings at different time lengths (maximum 90 min) at 1160 °C was investigated. Atomic scale characterization confirms that, on the one hand, the Mo interlayer prevents the Cr coating from reacting with the Zr substrate to form the ZrCr₂ Laves phase and, on the other hand, the solid solution structure generated due to Mo doping effectively guarantees the integrity of the Cr₂O₃ oxide layer and the residual Cr coating.

Mo中间层对Zr合金基体上Cr涂层氧化行为的影响

采用多弧离子镀方法在Zr基体上制备了含Mo中间层和不含Mo中间层的cr基涂层，研究了Mo中间层对涂层在1160℃下不同时间(最长90 min)氧化行为的影响。原子尺度表征证实，Mo中间层一方面阻止了Cr涂层与Zr衬底反应形成ZrCr2 Laves相，另一方面Mo掺杂产生的固溶体结构有效地保证了Cr2O3氧化层和残余Cr涂层的完整性。
