利用纳米粉末的特性,在纯铁粉中加入0.05wt%~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。 According to the characteristics of the nano-powder, nano-Cu powder of 0.05 wt% ~ 3 wt% is added into the pure iron powder, and then the manufacturing process of the nano-Cu powder is carried out successively, and then the density of the obtained sample is measured. The results show that adding a certain amount of nano-Cu powder can reduce the sintering temperature of the Fe-based powder metallurgy parts under the premise of meeting the required performance. When the addition amount of Cu is between 1% and 3%, the addition amount of nano Cu powder The decreasing trend of sintering temperature is obvious.
