Corrosion is a natural phenomenon that deteriorates a material as a result of an electrochemical attack by their environment. One way to mitigate or delay the effects of corrosion in metallic materials has been the development of metallic coatings. Deposition of tungsten alloys with one or more metals of the iron group provides high corrosion resistance and good mechanical properties. In this paper
a Fe-Co-W ternary alloy was electrodeposited varying the applied cathodic current density (10-50 mA/cm2) and deposition temperature (20-60 °C). The coatings were structurally and morphologically characterized by studies of energy dispersive spectroscopy (EDX)
scanning electron microscopy (SEM) and X-ray diffraction (XRD). Finally
the operational parameters regarding cathodic current efficiency and corrosion resistance were optimized. A factorial design 22 was adequately employed for experimental design analysis of the results. The deposited obtained under conditions 50 mA/cm2 current density
60 °C temperature
30 rpm cathode rotation and 7.0 had an amorphous character and showed good adherence
high corrosion resistance and presence of nodules on its surface. Electrochemical corrosion tests verified that the Fe-Co-W alloy had better corrosion resistance than similarly electrodeposited Co-W amorphous alloy

Finalmente, los parámetros operacionales en relación a la eficiencia de corriente catódica y resistencia a la corrosión fueron optimizados. Un diseño factorial 22 fue correctamente empleado para el análisis experimental de los resultados. Se observó que el deposito obtenido a condiciones de 50 mA/cm2 de densidad de corriente, 60 °C de temperatura, 30 rpm de rotación catódica y pH de 7.0, presentó una estructura amorfa y mostró una buena adherencia, alta resistencia a la corrosión y la presencia de pequeños nódulos en la superficie. Los ensayos de corrosión verificaron que la aleación Fe-Co-W tenía una mejor resistencia a la corrosión que la aleación amorfa Co-W electrodepositada de manera similar
