The search for new high performance coatings has experienced a relevant progress due to the recent
attention paid to the properties of nanostructured materials. In the last ten years a huge amount of results
have been published describing how nanostructured PVD coatings may exhibit excellent combinations
of different properties, including super- or ultra- hardness, extreme wear resistance, higher
toughness and corrosion resistance.
Most of these results have been achieved at laboratory scale. It seems that there is a real difficulty to
scale up these promising findings to exploitable industrial applications. By the way, this has been not
any obstacle for employing the mark “nano-“ in many commercial names of new coating introduced
in the market in the last five years.
This paper intends to make a review of most interesting strategies employed for the research groups:
nano-multilayers and nanocomposites approaches. A critical revision of the claimed new properties
is made, paying special attention to their possibilities of industrialization. Related problems like
techniques and standards to measure the coatings characteristics are also reviewed.
Keywords: PVD, multilayers, nanocomposites, industrial applications.
