中文摘要:
??????通过研究铝合金熔滴的垂直搭接过程中不同工艺参数下的对成形表面形貌和内部质量的影响规律。通过对单一金属液滴沉积行为研究,建立了垂直搭接沉积数值模型,并对多个熔融液滴垂直重叠形态的进化和温度变化过程进行分析和实验验证。实验表明:数值模拟与实验结果有良好的一致性,从而得到了最优参数。该研究对实现金属微液滴垂直搭接生产的有效过程控制至关重要,为制造复杂金属提供了技术支持和参考。

英文摘要:
??????During vertical lapped deposition with solidification of an aluminum molten droplet onto an aluminum substrate, the effects of the surface morphology and interior quality of the specimens under different process parameters were studied in this paper. By research of the single metal droplet deposition behavior, the vertical lapped deposition of numerical model was established, and the evolution of morphology and temperature of molten droplets vertical lapped deposition impacting a substrate surface at different time respectively and multiple droplets successively deposition experiments under the different simulation parameters were carried out. In order to confirm the numerical simulations and experimental verification, the comparison between numerical simulations and experiments shows a good agreement, and the optimal parameters are obtained. This investigation is essential to implement effective process control in metal micro-droplet deposition manufacture and it provides technical support and reference for the complex metal parts of molten droplets Vertical lapped deposition process.
