本文研究了铌离子注入对锆-4合金在400℃和500℃、10.3 MPa高压釜中蒸汽腐蚀行为的影响.试验结果表明:铌离子注入能够改善锆-4合金抗400℃和500℃高压蒸汽腐蚀性能,并且,比较而言对500℃蒸汽腐蚀性能提高的程度更为显著.为了理解铌离子注入影响的机理,应用SEM、XRD、XPS等分析手段分析了氧化膜的形貌、相结构、注入元素的价态及组成.

The influences of niobium ion implantation on autoclave steam corrosion performance were studied at temperatures of 400℃ and 500℃2, pressure of 10.3 MPa respectively. Experimental results prove that Nb ion implantation can improve the corrosion resistance of Zircaloy-4 against 400℃ and 500℃ high pressure steam. The improving extent of corrosion resistance at 500℃ was much more remarkable compared with that of400℃. In order to understand the influencing mechanism, scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoemission spectroscopy (XPS) were employed to analyze the morphology,phase structure of the surface oxide film, composition and valence of implanted element, respectively.
