Surface Modification of Aluminum Alloy 6060 through Plasma Electrolytic Oxidation

The impacts of electrical parameters throughout PEO development so they can be upgraded to deliver coatings with improved properties were contemplated. Alumina coatings were saved on 6060 aluminum amalgam substrates in a soluble silicate electrolyte utilizing a unipolar pulse DC current mode. The impact of preparing conditions, predominantly electrical parameters (frequency and duty cycle), on the arrangement, development conduct and properties of PEO coatings were researched. Distinctive portrayal techniques including checking electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffractometry, and contact tests were utilized to contemplate the microstructure, morphology and properties of the coatings. The connection between the phase of the PEO procedure and the properties of the covering were appeared. The voltage-time reaction was observed to be critical since it gave promptly quantifiable and helpful data about these stages. It was found that the microstructure, morphology, development rate, stage conveyance and organization of coatings could be changed by shifting the electrical parameters
