OBTENCIÓN Y EVALUACIÓN DE RECUBRIMIENTOS Ni-P MODIFICADOS CON MAGNETITAS SINTETIZADAS EN PRESENCIA DE Al y Ce Deposition and evaluation of Ni-P coatings modified with magnetites synthesized in presence of Al and Ce

Ni-P films modified with pure magnetite and magnetite synthesized in presence of Al and Ce were deposited. The oxide was obtained by hydrothermal route and in the presence of Al and Ce cations. The coatings were deposited by electroless plating and with co-deposition of magnetites. The coatings morphology was studied by means of scanning electron microscopy. The resistance to the corrosion of the modified Ni-P films with magnetite was evaluated by means of electrochemical impedance spectroscopy, where the composite films exhibited a better behaviour.
