The Discharge Characteristics of PEO Films in K2ZrF6 with NaH2PO4 Electrolyte
Keyword(s):
The discharge characteristics of the potassium fluorozirconate electrolyte during plasma electrolytic oxidation process were investigated. Sodium dihydrogen phosphate was applied as additives. Ceramic films were prepared on magnesium alloy in electrolytes with different content additives under constant voltage. The effect of additives on the pH of the electrolyte and the dissolution of the substrate were investigated. It was found that the additives could influence the pH and dissolved magnesium ions effectively.
