Personal Computer Controlled Installation for Plasma Electrolytic Treatment Process Control

Plasma electrolytic treatment of metals is a new emerging technology that features high quality, cost effective and environmentally friendly surface engineering. The main difference between plasma electrolytic treatment and conventional electrochemical treatment are operation at high voltages in the range 100-500 V and application of low concentration water solutions of non-toxic salts. The phenomenon of plasma electrolysis is being currently researched mainly in Russia, UK and USA. However, process control issues appear to be less investigated. Moreover, the installations described in the references either lack computer control or serve phenomenon investigation, not process control. This paper describes the computer-controlled installation, which serves investigation of the plasma electrolytic treatment process control.
