This paper presents the results of experimental studies carried out to conduct a comprehensive investigation on the influence of ultrasonic vibration of workpiece on the characteristics of Electrical Discharge Machining (EDM) process of FW4 Welding Metal in comparison with the conventional EDM process. The studied process characteristics included the material removal rate (MRR), tool wear ratio (TWR), and surface roughness (Ra and Rmax) of the workpiece after the EDM and ultrasonic assisted EDM (US-EDM) processes. The experiments performed under the designed full factorial procedure and the considered EDM input parameters included pulse on-time and pulse current. The experimental results show that in short pulse on-times, material removal rate in the US-EDM process is approximately quadruple than that of the EDM process. On the contrary, in the long pulse on-times, ultrasonic vibration of work??piece leads to the reduction in the MRR. On the other hand, in short pulse on-times, the TWR in the US-EDM process is lower than that of in the EDM process, and this condition reverses with increase in the pulse on-time. Furthermore, the surface roughness of the workpiece machined by EDM process is slightly lower than that of applied to the US-EDM process.

镨是支持全球清洁能源发展的关键矿产,全球对镨的需求持续增加。我国是全球镨储量和产量最大的国家,但是未来依然可能出现镨供给缺口,发展循环经济、促进物质循环利用是解决镨潜在供需受限问题的重要方案。本文采用动态物质流方法,结合循环利用率指标,估算了2011—2020 年我国大陆地区的镨循环利用潜力。结果表明:2011—2020 年,我国累计有7.902×104 t 镨进入镨循环,其中1.639×104 t 来自循环利用;从钕铁硼磁体生产废料中累计回收利用了1.369×104 t 镨,其循环利用率稳定在17%左右;理论上,报废产品可以供给2.7×103 t 镨,其循环利用率从0.04%增长到5.17%。针对实现报废产品中镨循环利用所面临的主要挑战,本文提出了完善我国生产者责任延伸制、逐步建立相关产品的消费者责任制、引导行业制定循环利用相关技术规范和行业标准等镨循环利用提升策略。
