Abstract

The resource of plasma torches and plasma devices on their basis depends strongly on the rate of destruction (erosion) of the electrodes. Experimental data on the erosion of copper electrodes in DC arc plasma torches are presented. In dependence on the design of plasma devices and their technological applications, the electrodes (cathode and anode) are in different thermal conditions and their resource characteristics differ significantly. The key parameters for optimization of the erosion characteristics during operation of plasma torches with an electrode resource of many hundreds of hours have been established.

电弧等离子炬中管状铜电极的资源特性1

摘要

等离子炬和等离子设备的资源很大程度上取决于电极的破坏（侵蚀）速度。给出了直流电弧等离子炬中铜电极腐蚀的实验数据。根据等离子体装置的设计及其技术应用，电极（阴极和阳极）处于不同的热条件下，其资源特性也有很大差异。已经建立了在电极资源为数百小时的等离子炬运行过程中优化腐蚀特性的关键参数。
