利用扫描电镜、能谱仪、X射线衍射仪以及自行设计制造的机械能助渗装置和自己开发的渗铜剂 ,研究了机械能助渗铜工艺及其组织结构。将渗铜温度由常规的 1 1 0 0℃降低到 42 0～ 460℃ ,保温时间由 4～ 8h减少到 1～ 2h ,节能效果十分显著。渗铜层由断续 (有时连续 )岛状白亮层、黑色中间层和紧靠基体的白亮层组成。渗层中白色组织为溶解少量铁的铜固溶体 ,黑色组织为屈氏体。
Using mechanical scanning electron microscopy (SEM), energy dispersive spectroscopy (XRD), X-ray diffraction (XRD) and mechanical energy permeation control device designed by ourselves and the copper infiltrating agent developed by ourselves, the mechanical energy-assisted infiltration process and its microstructure were studied. The temperature of copper infiltration was reduced from 110 ℃ to 42 0 ~ 460 ℃, and the holding time was reduced from 4 ~ 8h to 1 ~ 2h. The energy saving effect was very significant. The copper infiltration layer is composed of intermittent (sometimes continuous) island-like white bright layers, black intermediate layers, and white bright layers next to the substrate. The infiltration of white tissue to dissolve a small amount of iron copper solid solution, black tissue troostite.
