“…However, the rapid corrosion rate in the physiological environment has become the main drawback, which is hindering their applications. [1][2][3][4] The rapid corrosion of magnesium alloys results in the loss of their mechanical integrity before sufficient bone tissues are recovered. Moreover, rapid corrosion of Mg results in many other adverse effects, including the formation of hydrogen gas cavities and increase of local pH, which is harmful to tissue healing.…”

“…Recently, there has been much attention paid to magnesium alloys in the biomedical field due to their low density, high specific strength, good biocompatibility, and similar mechanical properties to natural bone [1][2][3]. Magnesium is an essential element in the human body, and magnesium alloys can induce the formation of new bone when they are used as bio-absorbable implants [4,5]. However, the rapid degradation of magnesium alloys limits their applications because of their high corrosion rates [6].…”

“…Uno de los principales desafíos consiste en desarrollar materiales no tóxicos y con buena estabilidad mecánica al momento de su aplicación [1][2][3][4]. Entre los más estudiados se puede mencionar a los polímeros, cerámicos y biovidrios, fundamentalmente por su capacidad para ser reabsorbidos o degradados después de cierto tiempo de ser implantados, sin generar productos tóxicos en el organismo receptor [5][6][7][8]. Otro reto que presentan los materiales bioactivos se basa en determinar la relación que existe entre la velocidad de reabsorción vs la velocidad de sustitución por tejido nuevo sin comprometer sus propiedades estructurales, manteniendo tanto la resistencia como así también la estabilidad interfacial durante el período de incubación [9,10].…”

“…Sin embargo, luego del sinterizado, su estructura cristalina se modifica reduciéndose la capacidad bioactiva resultante [27]. Por lo tanto, una alternativa que permite superar esta limitación consiste en desarrollar recubrimientos bioactivos que no necesiten tratamientos térmicos posteriores [8]. Así, la co-deposición electroforética (co-EPD) de mezclas de polímeros y vitrocerámicos es una alternativa viable para obtener recubrimientos que presenten una adecuada adherencia al sustrato metálico sin comprometer la bioactividad final del material [14,25].…”
