Optimizing the electrolyte chemistry parameters of PEO coating on 6061 Al alloy by corrosion rate measurement: Response surface methodology

•A regression equation was developed based on the corrosion behavior.•The best corrosion behavior is resulted by lowest porosity and highest thickness.•Electrolyte chemistry affected on micro-structure and thickness of PEO coatings. Different chemistry parameters of electrolyte, including KOH, Na2Si...
