摘要

摘要: 利用铸渗法对铜合金表面进行改性, 用Fe 基合金粉末作为渗剂在负压条件下进行浇注制备铜基表面复合材料。实验结果表明: 在本实验工艺条件下, 在铜合金铸件的特定表面获得了致密的组织结构不同于基体的渗层———表面复合材料层。经SEM 观察, 发现渗剂颗粒与基体的界面结合良好, 证实了铸渗法制备铜基表面复合材料的可行性。

Abstract: The surface of copper alloy was modified using infiltration casting. Fe-based alloy powder was used as infiltrated agent under the condition of negative pressure to form the infiltrated layer on the surface of copper cast . The experimental results show that the surface composites of copper matrix are obtained under the present condition , whose structureis different from that of the substrate. The SEM shows that the interface between the base metal and the penetrated layercontains no exist holes and the structure is compact . Infiltration casting is feasible to fabricate the surface composite of acopper substrate.
