abstract = "In this work, the fretting wear behavior and adhesion of DLC
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.",
