摘要
利用纳米粉末的特性，在纯铁粉中加入O．05wt％-3wt％的纳米Cu粉，先后进行混料、压制和烧结等制造工序，然后将得到的试样进行密度测定。结果表明，在达到要求的使用性能前提下，添加一定量纳米Cu粉可降低Fe基粉末冶金制件的烧结温度；当Cu的添加量在1％～3％时，纳米Cu粉末的添加量对烧结温度的降低趋势较为明显。
Taking use of the characteristics of nano-powder to add nano-Cu powder with 0.05wt%-3wt% into pure iron fine. The manufacturing processes of material mixing, pressing and sintering were conduct the and then the density and hardness of the sample was measured. The results show that the addition of certain amount of nano-Cu powder can decrease the sintering temperature of Fe-based powder metallurgy component at the premise of complying with required usability; when the dosage of Cu is between 1%-3%, the amount of nano-Cu powder can obviously reduce sintering temperature.
