【摘要】 利用ＡＥＳ、ＷＤＳ和ｘ－射线衍射等方法，研究了杜美丝表面层、铁镍芯与覆铜层界面的微观结构与特性。结果表明：良好的表面层应由Ｃｕ２Ｏ和非晶态的硼砂构成；玻璃与杜美丝的润湿性决定于表面层的净化程度和构成及加热条件。更多还原

【Abstract】 This paper introduced the research about the micro structure and the properties of the surface layer and the ferronickel core-copper clad boundary layer of dumet wire by means of AES、WDS and x-ray diffraction. The results show that the good surface layer consisting of a mixture of Cu2O and noncrystalline borax;The wettability between the glass and dumet wire depends on both the cleanliness and constitution of surface layer and the heating conditions.更多还原
