Resumen:
This work reports on the features that NiW nanostructured
alloys, electrodeposited on carbon steel by different
current pulse programs, may present depending on their surface
morphology and surface composition. The NiW nanostructured
coating, with a cauliflower structure, lack of
fragility, and high WO3/W surface composition ratio, is a
stable electrode to catalyze hydrogen evolution reaction, exceeding
bulk and electrodeposited Ni catalytic activity. Also,
the nanostructured alloys must have a low WO3/W surface
composition ratio for Ni and its oxides to provide protection
and improve corrosion resistance in sulfate media.
