abstract = "Pure chromium coatings can act as decorative or
corrosion-resistant coating, but they present poor tribological
properties. Even electroplated hard chrome coatings present some
problems, as micro-cracks that reduce their corrosion protection
and induce fatigue failure. In addition, Cr plating and its
dangerous process with Cr VI baths has been banished in several
countries. Physical or chemical post-coating treatments can be
applied onto coatings in order to enhance their surface
properties, as high temperature oxidation, chemical baths or ion
implantation. Plasma immersion ion implantation process was
carried on PVD chromium coatings as a post-coating treatment and
nitrogen ions were implanted on the surface of deposited chromium
thin films, by means of two different plasma sources for ion
implantation. Both configurations for plasma sources led to the
formation of nitride compounds on the surface of the films. The
treated films presented low coefficient of friction, high hardness
and better adhesion when compared to the untreated film.",
