摘要
设计并自制了雾化设备,通过对主要雾化参数的调整,制备了Cu-Ag合金颗粒,借助体相显微镜以及X射线衍射仪,对雾化合金颗粒的形貌和物相进行了观察和检测,分析主要雾化参数对Cu-Ag合金颗粒粒度及形貌的影响。结果表明,雾化制备的颗粒主要为球形或类球形;合金中Ag因较好的固溶进Cu中而没有单独成相;制备尺寸为150～900μm的Cu-Ag合金颗粒的最佳雾化参数是漏嘴孔径为3.6～4.1mm、浇注温度为1578～1591℃、雾化气压为3.0～3.4MPa。
We have developed an atomizing device to prepare Cu-Ag alloy particles by adjusting the main atomizing parameters. With the help of body phase microscope and XRD（X-ray diffraction）, the morphology and phase of atomizing particles were observed and tested to understand effects of the main atomizing parameters on particle size and morphology. The results show that atomizing particles exhibit mainly spherical or near-spherical structure. Ag has preferably dissolved into Cu and not separated into the single phase. The suitable atomizing parameters for preparing Cu-Ag alloy particles with 150-900 μm were presented as follows： package leakage aperture of 3.6-4.1 μm, pouring temperature of 1 578-1 591 ℃ and atomizing pressure of 3. 043.4 MPa.
