                         coatings deposited by PACVD on nitrided and non-nitrided 
                         martensitic stainless steels were studied. Fretting wear tests 
                         were carried out with different duration and loads and pin-on-disk 
                         was also performed. The adhesion was evaluated by Rockwell C 
                         indentation and scratch test with constant and variable loads. The 
                         coating thickness was 2.5 mu m and the nitrided layer, 11 mu m The 
                         coating hardness and Young's Modulus were about 16 and 110 GPa, 
                         respectively. The duplex samples resulted with better adhesion 
                         than the only coated samples in all test conditions. In the 
                         scratch test, the critical load in the duplex sample was 58 N and 
                         in the coated sample, 12 N, showing a brittle failure mode. In the 
                         Rockwell C indentation test, the adhesion was better in the duplex 
                         sample because the nitriding treatment changed the failure mode of 
                         the system. The wear resistance was also related to adhesion, 
                         since in the experiments with high loads and long durations 
                         adhesive failures could be detected when stresses reached the 
                         interface and the substrate. In the duplex sample, the nitrided 
                         case, with higher load bearing capacity than the substrate, 
                         resulted in a better wear behavior of the system.",
