APPLICATIONS of THIN FILMS
In the previous chapter, the concept, classiﬁ cation, and technical properties of nanocomposite and nanostructured thin ﬁ lms and coatings have been introduced. In addition, important and popular thin-ﬁ lm deposition techniques and principles have been reviewed. For a variety of applications, different structures and properties of a nanostructured and nanocomposite coating system are required, leading to speciﬁ c coating design and correlated deposition process parameter control. In general, nanocomposite coatings can demonstrate different mechanical, electrical, optical, electrochemical, catalytic, and structural properties than those of each individual component . This multifunctional behavior is closely connected to the ﬁ lm structure. The structure, however, depends on the phases, chemical composition, and the arrangement of the phases in the material and this in turn is strongly governed by the deposition process.
