The development of a method for deposition of low‐density polyethylene (LDPE) on rotating three‐dimensional aluminum alloy substrates is presented. LDPE powder with an average diameter of 50 
m is dispersed with nitrogen as a carrier gas. This suspension is injected into a plasma plume generated by a pulsed atmospheric arc plasma jet (PAA‐PJ). The optimized PAA‐PJ operating parameters are a pulse frequency of 63 kHz, a power of 1,500 W, a plasma gas (mixture of nitrogen with 3.3% hydrogen) flow of 54 SLM (standard litre per minute), a carrier gas flow of 9 SLM, and a powder rate of up to 5 g/min. The plasma head is moved at 200 mm/s, and the substrate is rotated at 10 rev/min. The net deposition rate reaches 2.5 g/min. A homogeneous, high‐quality film with 1‐mm thickness is deposited on an approximately 100 cm2 substrate surface.

脉冲大气压电弧等离子体射流在低密度聚乙烯涂层中的应用
提出了一种在旋转的三维铝合金基板上沉积低密度聚乙烯（LDPE）的方法的开发。将平均直径为50m的LDPE粉末 分散在氮气中作为载气。将此悬浮液注入由脉冲大气压电弧等离子流（PAA-PJ）产生的等离子羽流中。优化的PAA-PJ操作参数是脉冲频率为63 kHz，功率为1,500 W，等离子气体（氮气与3.3％氢的混合物）流量为54 SLM（每分钟标准升），载气流量为9 SLM，粉末速率最高为5 g / min。等离子头以200 mm / s的速度移动，基板以10转/分钟的速度旋转。净沉积速率达到2.5 g / min。在约100 cm 2上沉积厚度为1mm的均匀，高质量的薄膜 基材表面。
