  Effect of target processing on CoCrPtTa thin-film media

  摘要：

  接下来的论文总结了关于靶材微观结构形态对溅射沉积介质磁性能影响的研究。具有相同化学成分的 Co-Cr-Pt-Ta 靶材在相同条件下溅射，但具有不同的微观结构相和晶体纹理特征，因此介质磁矫顽力存在显著差异。造成这一结果的原因很可能是两种不同靶材微观结构中含 Ta 相的溅射产率不同。研究结果表明，铬偏析增强导致沉积薄膜的粒间交换能场降低。

  A one-component adhesive for metal surfaces such as iron, zinc, copper, cadmium and their alloys will cure upon contact with the metal surface. The adhesive composition includes olefinically unsaturated monomer; reactive or nonreactive polymer; an acidic material; a compound containing sulfonyl halide group; and a compound containing a transition metal. The adhesive composition cures rapidly upon contact with a metal surface to form an adhesive bond between the surfaces. The adhesive composition is especially useful as a thread-lock adhesive, and as an adhesive for bonding structural components.
