Process control parameters of nano structured stainless steel surface through the plasma electrolytic technology

摘要

The aim of this research is to confirm the plasma electrolytic reaction zone for the reaction system assembled. At the same time, research shows how the plasma reacts when the clearance between two polarities is adjusted. The specimen used SUS316 stainless steel and the electrolytic solution was water-based sodium bicarbonate. All specimens are processed by polishing and grinding. To identify the zones of plasma electrolysis by measuring the voltage-current curve, the voltage increased continuously and observed the current variation at the same time. According to the voltage value is shown that the plasma electrolysis at 220 V-240 V is in a stable zone. Therefore, the voltage used is 220 V-240 V and the frequency was 50 kHz. In this research, the current density should be used as an index parameter for the plasma electrolytic reaction zone and the voltage value result is more accurate.
