Abstract

Se evaluaron recubrimientos Ca-P obtenidos por un método potenciostático catódico a partir de una solución sobresaturada en iones calcio y fósforo, mediante EIS, con el fin de caracterizar el comportamiento electroquímico en un fluido simulado Ringer`s. El pH (5.0 y 10.0), concentración de Ca/P de la solución precursora del recubrimiento (Ca/P) (1.00 y 1.5) y voltaje catódicos (9 V, 12V y 15V), influyen sobre la respuesta resistiva. Las relaciones Ca/P en el recubrimiento se ha cuantificado por medio de Espectroscopia de Energía Dispersa (EDS) y la morfología del depósito obtenido fueron analizadas por medio del Microscopia Electrónica de Barrido (SEM)
