    摘要:

    本文采用尿素高溫分解產生的氧化性氣氛在氫化鋯表面制備多元復合膜層。利用XRD、SEM、EDS、XPS、AES等分析測試手段對氫化鋯表面膜層的相結構、截面形貌、元素成分及價態(tài)進行性能表征。物相分析結果表明膜層主要有氧化鋯相和ZrN相,且氧化鋯相由單斜相(m-ZrO2)和四方相(t-ZrO2)組成。掃描電鏡形貌分析表明原位生長氧化物膜層致密,膜層與氫化鋯基體結合緊密。俄歇電子能譜結果表明膜層由C、N、O、Zr元素組成,并具有明顯的分層現象,膜層由外向內分為富(C/N)層及富O層,隨膜層表面濺射時間增加,O、Zr元素相對含量明顯增加,C、N元素相對含量明顯降低。X射線光電子能譜分析表明多元復合膜層存在Zr-O、Zr-C、Zr-N-O、Zr-N、O-H等鍵,C、N、O原子協(xié)同作用,使涂層具有較好的阻氫滲透作用。

    Abstract:

    Coatings for preventing hydrogen escaping were formed on disk-type ZrH1.8 by in-situ oxidation method. Urea was placed and in vacuum chamber and decomposed into complicated chemical compound including carbon, nitrogen, oxygen source. The phase structure and morphology of coatings were analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM). The composition and depth of elements, bond states were tested by auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) technique. The results indicate that weight of coatings increased with temperatures rised. XRD shows the phase structure of coatings consists mainly of ZrN and ZrO2, including monoclinic ZrO2 (m-ZrO2) and tetragonal ZrO2 (t-ZrO2). SEM depicts coatings were accumulated and combined densely with substrate. AES indicates that the coating is mainly composed of carbon, nitrogen, oxygen and zirconium, which show that the atomic concentration of carbon and nitrogen decreased continuously, while, oxygen and zirconium increased with sputter time incresing. XPS shows that coating was including Zr-O、Zr-C、Zr-N-O、Zr-N、O-H bonds. It is possible the C, N, O atoms synergistic effect, making the coating has good resistance hydrogen permeation.
