                         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.",
