This chapter illustrates the use of electrodeposition to produce
multifunctional nanostructured metallic coatings. Such coatings can
provide several engineering functionalities, including wear and cor-
rosion resistance to provide an eﬀective tribological performance.
This chapter is divided into three parts. The ﬁrst part provides a
concise overview of the principles of electroplating and anodising.
The next part explains the strategies adopted to electroplate
nanostructured metallic coatings, which include (a) grain reﬁne-
ment, (b) application of a modulated current, (c) inclusion of
nanoparticles into the coating and (d) use of nanoporous templates.
The ﬁnal part provides examples of multifunctional tribological
properties of coatings illustrated by research ﬁndings from our
laboratory and the literature. Multifunctional nanostructuredmetal-
lic coatings include (a) nanocrystalline, (b) functionally graded
and (c) nanocomposite types. Such coatings can provide improved
corrosion andwear resistance, decreased friction and longer service
