Abstract
Abstract Phytic acid has been used to generate phytate conversion coatings on magnesium and magnesium alloys, in order to improve their corrosion resistance without jeopardizing their biocompatibility and biodegradability. In the present work, statistical designs were used to determine the optimal levels of the parameters for the formation of a conversion coating on {AZ31} Mg alloy, with the aim of using it for further endoprosthetic temporary applications. Both parametric and non-parametric statistical tests were used to determine the optimum processing parameters of the coating on the {AZ31} magnesium alloy, which are: phytic acid concentration of 0.5%v/v, pH = 5, treatment time of 30 min and treatment temperature of 29
