Experimental Test Report An Investigation of Alternative Copper Infiltration Techniques

摘要

An experiment was conducted to investigate the feasibility of a new copper infiltration technique. The purpose of this research was to improve the robustness of the process, specifically to develop a new copper infiltration method that would eliminate the handling of green copper compacts. The processes compared are conventionally compacted copper powder infiltrants; additional copper powder simultaneously compacted into the iron compact by means of layering the powders during die filling; and the use of copper stampings to facilitate the infiltration process. Comparisons will be made with respect to sintered dimensional change, erosion, residue, and physical and mechanical properties.
