摘要
本文以铁粉为原料,采用金属粉末烧结法,在温压工艺不同的情况下,制备出了具有多孔性能的铁基金属材料。并通过正交试验研究了聚合物质量百分比、压制压力和压制温度对烧结制件孔隙率和力学性能的影响规律。试验结果表明:高分子聚合物对烧结件性能起着重要的作用,同时具有造孔功能,当聚合物质量百分比为4%～5%时,多孔铁制品的孔隙率与力学性能同时达到稳定状态;压制温度为140℃时,高分子聚合物的作用发挥到最佳。
This paper deals with the effects of warm compaction on fabrication of porous Fe in P/M. Using orthogonal tests as the major method, the effects of macromolecule polymer content, compacting pressure and compacting temperature in warm compaction on structure and mechanics function were studied. The experiment result shows that macromolecule polymer is very important for the performance of sinter products, and provided with porous function. Porous Fe has a simultaneous steady phase of structure and mechanics function on the conditions of macromolecule polymer at the range of 4%～5%. When compacting temperature is 140℃, macromolecule polymer performs the best effect.
