摘要
利用自制的注射3D打印成型机,对铜浆料进行成型,然后进行烧结,实验研究了铜浆料的烧结工艺并进行参数优化,通过微观组织分析烧结样品产生缺陷的原因。通过改变烧结过程的烧结温度、保温时间,采用SEM、TGA、金相显微镜等手段观察分析。结果表明:烧结温度为950℃、保温时间为90 min时,可以烧结出质量较高的样品,其相对致密度最终可以达到90%,硬度达到77.98 HV。
The copper paste was formed by homemade injection 3D printing, and then was sintered at high temperature. The sintering process and parameters of the samples were optimized under different sintered temperatures and hold times, and the causes of the sintered defects were analyzed by microstructure observation. The results show that the relative density can eventually reach 90% and the hardness is up to 77.98 HV under the sintering temperature of 950 ℃ and the holding time for 90 min.
