摘要:
利用研制的高频纳秒脉冲电源放电烧蚀钛电极合成了纳米钛颗粒,并探究了电源频率、冷却气体流量等对合成的钛颗粒粒径的影响规律.进而,开展了纳米钛颗粒的燃烧特性研究.结果表明,所研制的纳秒脉冲电源满足实验需求,且随着电源放电频率的提高以及冷却气体流量的降低,合成的钛颗粒粒径逐渐增大;而燃烧实验结果则表明,链状纯钛颗粒团聚体(一次粒径小于10,nm)的燃烧时间随其电迁移率当量直径的变化不大.
Abstract:
In this paper,nano-sized titanium particles were synthesized by using a self-designed high-frequency nanosecond pulse discharge to ablate the titanium electrode.The effects of power frequency and the flow rate of quenching gas on the size of the synthesized titanium particles were examined.The combustion characteristics of nano-sized titanium particles were studied.The designed power supply well meets the experimental requirements and the results indicate that the size of the synthesized particles increases gradually with the increasing discharge frequency and the decreasing flow rate.The further combustion experimental results show that the burning time of dispersed titanium particle agglomerates consisting of primary particles with the size below 10,nm changes little with the variation of the mobility equivalent spherical diameter of the particle.
