自动高能微弧火花表面冶金处理机电极控制器研究

摘要

介绍了高能微弧火花表面冶金处理机自动电极控制器的研制 ,实现了金属表面处理机由手动操作到自动的转变 ,初步解决了制约这一技术推广应用的瓶颈问题.通过采集和分析电火花放电间隙的电压、电流脉冲 ,实现了连续、稳定的放电控制.通过现场试验、调试 ,验证了此电极控制器能够很好地连续、稳定工作 ,实现了对平面工件、坡面工件和多种花样图案工件的强化与修复.%This paper introduced the development of an automatic electrode controller for high-energy micro-arc spark surface metal-lurgy processor .By use the controller ,the change from manual to automatic repair and reinforcement of metal parts wear surface is realized ,so that the bottleneck problems of restricting this technology popular has been preliminarily solved .Through the sampling and analysis of the voltage pulse and current pulse of the spark discharge gap ,the continuous and stable discharge control is realized by the electrode controller .The experiment and debugging show that the electrode controller works continually and stably and the re-pair of the surface of metal parts is realized .
