采用金属等离子体基离子注入的方法,在 Ag基体上注入了 Al.用 X射线光电子能谱仪(XPS)对注入层的 Al浓度一深度分布和化学态进行了分析.用x射线衍射法(XRD)对注入层和非平衡磁控溅射的则沉积层相组成进行了测定和比较,选用小掠射角(3°)XRD对注入层的相组成进行了测定.结果表明,注入层中 Al浓度沿深度方向逐渐降低,表面有 Ag原子存在;近表面处形成了 Ag-Al固溶体并且出现了少量的 μ-Ag3Al相;较深处有氧化铝的形成,出现 Ag—Al固溶体、 μ—Ag3Al相和氧化铝三相共存;更深处, Al含量很快下降, Ag-Al固溶体消失,出现μP-Ag3Al相和氧化铝共存 μ-Ag3Al相为β-Mn复杂立方结构,可以在很宽的 Al含量范围内形成,而 Al沉积层中未出现 Ag3Al相
Using metal-based plasma-based ion implantation method, Al was implanted into the Ag matrix. The Al concentration-depth distribution and chemical state of the implanted layer were analyzed by X-ray photoelectron spectroscopy (XPS). The phase composition of the deposited layer and the non-equilibrium magnetron sputtering deposited layer were measured and compared by X-ray diffraction (XRD). The phase composition of the implanted layer was determined by X-ray diffraction (XRD). The results show that the concentration of Al in the implanted layer gradually decreases along the depth direction, and there are Ag atoms on the surface. Ag-Al solid solution is formed near the surface and a small amount of μ-Ag3Al phase appears. -Al solid solution, the μ-Ag3Al phase coexists with the three phases of alumina. At deeper depths, the content of Al decreases rapidly and the Ag-Al solid solution disappears. The μ-Ag3Al phase coexists with the μP-Ag3Al phase as the β-Mn complex cubic structure , Can be formed over a wide range of Al contents, while the Ag3Al phase does not appear in the Al deposit
