Resumo
In this work, composite Ni–P-multiwalled carbon nanotube films were produced by electroless
deposition. The main goal was to investigate the influence of multiwalled carbon nanotube
loading on the local electrochemical behavior of the composite films, as probed by scanning electrochemical
microscopy (SECM). The coatings were also characterized with respect to their crystalline
structure, surface, and cross-section morphologies. Adhesion strength was examined by scratch
tests. The global electrochemical behavior was evaluated by potentiodynamic polarization. The local
electrochemical activity was investigated by probing the Fe2+ oxidation in the surface generation/tip
collection mode of the SECM. The results revealed that multiwalled carbon nanotubes increased the
adhesion strength and reduced the electrochemical activity on the surface of the coated samples.
