Electrochemical methods for the preparation of high quality
nanostructured surfaces and functionalization through active
biomolecules electrodeposition are highlighted in this work.
There are two applied electrochemical methods in our laboratory
in order to obtain hybrid and nanocomposite structured layers or
advanced functionalization of material surfaces. They are direct
electrochemical synthesis by electro codeposition process and
anodization of materials to controlled growth of nanoporous
oxide films and the second method could be followed by
electrodeposition of hydroxyapatite or organic compounds into
porous films to form more complex hybrid layers. The main goal
of the present paper is to make a summary of results obtained
from applying electrochemical surface modification techniques
in obtaining advanced functional surfaces and their properties
characterization in terms of surface morphology and structure
(SEM-EDX, XRD), the roughness and thickness, corrosion,
tribocorrosion as well as the mechanical properties as nano
hardnessorwearresistance.Electrodepositionofmetalsandalloys
or electro-codeposition of nano andmicrodispersed particleswith
metallicmatrixtoobtainmicroandnanostructuredfilmsandlayers
or hybrid coatings are a bottom-up approach of nanotechnology
methods. Electrochemical oxidation or anodization to obtain thin
films, layers of nano porous oxides, templates for nanowires or
active biomolecules electrodeposition is a top down approach of
nanotechnology method. Electrodeposition and the combination
of electrodeposition with other electrochemical processes as
controlled oxide growth by anodization can lead to a large class
of hybrid layers and composite coatings or nanostructured layers
(films) on different support materials and structures necessary
for a future based on nanotechnology and nanomaterials to
improve the surface functionalization of materials and to face of
aggressive environments and degradation processes. Improving
surface properties for corrosion and tribocorrosion of materials
in specific environments give more valuable industrial and
biomedical applications by increasing their life cycle.
