本文报道了30 mm宽的大气压冷空气等离子体刷。由直流电源驱动的电刷能够在没有惰性气体添加和没有气流补充的情况下产生空气等离子体辉光。没有辉光到电弧过渡的风险,并且无论加工何种材料,等离子体辉光都是均匀的。通过使用等离子体刷阵列,可以放大空气等离子体辉光。通过七个电刷阵列的合并,产生了约30mm × 30mm × 5mm(宽、高、长)的均匀空气等离子体辉光。电流测量结果表明,单刷放电呈现周期性脉冲,而刷阵列放电实际上呈现约阵列数倍于单刷放电频率的脉冲。进一步的分析表明,电荷粒子捕获沿着电介质表面可能是负责的放电。
In this paper, 30-mm-wide cold atmospheric-pressure air plasma brushes are reported. The brushes driven by a direct current power supply are capable of generating air plasma glows with no noble gas addition and no airflow supplement. There is no risk of glow-to-arc transitions, and the plasma glow appears uniform no matter what kinds of material are being processed. The air plasma glow can be scaled up by using the plasma brush arrays. About 30mm × 30mm × 5mm (W, H, and L) homogeneous air plasma glow is generated by merging seven-brush arrays. Current measurements show that the single-brush discharge appears periodically pulsed, while the brush array discharge actually presents either pulsed with about array-number-times frequency of the single one. A further analysis indicates that the charge particles trapped along the dielectric surface may be responsible for the discharges.
