Abstract

In this research, porous plasma electrolyte oxidation (PEO) coatings were prepared on AZ31 magnesium alloys with the aim of investigating how PEO competitive mechanism affects the coating properties. Thickness of the coated layer, surface morphology, phase structure and quantitative information about porosity were analyzed by FE-SEM, XRD and MATLAB software. The result showed that PEO competitive mechanism was influenced by process parameters such as time, current density, conductivity and breaking voltage. It was concluded that the competition between dissolution rate of magnesium alloy and ceramic coating formation, determines the pore size, thickness and porosity of coating, which are of great importance in bone cell interlocking after implantation. Moreover, various phosphate salt solutions were studied in terms of conductivity. It was concluded that, the degree of phosphate hydration and hydrogenation affects the conductivity and pH of electrolyte. Also, hydrogenated phosphate ions, caused the formation of PEO coating layer including non-adhesive compound which prevented plasma sparking.
