| 摘 要： | 对SnAgCu合金粉末的真空蒸镀涂层硬脂酸的成膜机理进行了研究.采用扫描电镜(SEM)和透射电镜(TEM)对涂覆后合金粉末的形貌及结构进行观测,采用傅里叶红外光谱仪(FTIR)和X射线光电子能谱仪(XPS)对涂覆后粉末的透射吸收谱和光电子能量进行测试.结果表明:硬脂酸在合金粉末表面形成一层均匀致密、厚度为5～10 nm的薄膜,硬脂酸涂层SnAgCu合金粉末的行为属于物理吸附行为,其生长方式遵循岛状生长机理模式,其过程实质是一个气--固转换、晶体生长的过程.

| Abstract: | The film-forming mechanism of stearic acid modified SnAgCu alloy powders by vacuum evaporation was researched.Scanning electronic microscope(SEM) and transmission electronic microscope(TEM) were used to observe the morphology and structure of the coated powders.Fourier transform infrared spectroscopy(FTIR) and X-ray photoelectron spectroscopy(XPS) were adopted to test the transmission absorption spectrum and photoelectron energy of the coated powders.The results indicate that uniform and compact coatings wh... |
