中文摘要:
      本文采用尿素高温分解产生的氧化性气氛在氢化锆表面制备多元复合膜层。利用XRD、SEM、EDS、XPS、AES等分析测试手段对氢化锆表面膜层的相结构、截面形貌、元素成分及价态进行性能表征。物相分析结果表明膜层主要有氧化锆相和ZrN相,且氧化锆相由单斜相(m-ZrO2)和四方相(t-ZrO2)组成。扫描电镜形貌分析表明原位生长氧化物膜层致密,膜层与氢化锆基体结合紧密。俄歇电子能谱结果表明膜层由C、N、O、Zr元素组成,并具有明显的分层现象,膜层由外向内分为富(C/N)层及富O层,随膜层表面溅射时间增加,O、Zr元素相对含量明显增加,C、N元素相对含量明显降低。X射线光电子能谱分析表明多元复合膜层存在Zr-O、Zr-C、Zr-N-O、Zr-N、O-H等键,C、N、O原子协同作用,使涂层具有较好的阻氢渗透作用。

英文摘要:
      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.
