Glow Discharge Cleaning

Figure 5. Observed change in the elemental surface composition of hydrocarbon-covered 304 stainless steel and Inconel as a function of exposure to hydrogen discharge cleaning. The stainless steel sample was exposed to glow discharge cleaning in the PDXTokamak (Ref. 37J and the Inconel sample was exposed to pulse discharge cleaning in the TFR Tokamak. Key , C SS substrate A, O SS substrate ...

The most important parameters in glow-discharge cleaning are the type of applied voltage (AC or DC), the value of discharge voltage, the current density, type of gas and gas pressure, duration of treatment, type of material to be cleaned, shape and arrangement of electrodes.
