Resumen:
Ni-W nanostructured coatings electrodeposited on steel by galvanostatic pulses were functionalized by tetraethoxysilane (TEOS) and octadecyltrichlorosilane (OTS) in a two-step procedure. A silica-rich layer is formed by the reaction of TEOS with the metal coating surface oxides, which allows a further reaction with OTS forming a hydrocarbon?silica outer network. This mixed silane layer provides hydrophobicity and improves the corrosion behavior of the Ni?W surface coatings without modifying their excellent mechanical properties.
