abstract = "Precipitation hardening stainless steels are extensively used as a
material for plastic injection dies because of their dimensional
stability during hardening, impact strength and wear and corrosion
resistance. Plasma surface engineering can enhance even more the
working life of these components preserving them from wear and
corrosion damage by means of surface modification or coatings. In
this work PH stainless steel Corrax® was ion nitrided and coated
with DLC in a modified PACVD duplex process. DLC films are known
not only for their hardness but also for their low friction
coefficient, features that improve the wear resistance of steel
components. Adhesion tests were performed; wear resistance was
tested in a pin on disk machine with different counterparts and in
the abrasion ASTM G65 test. Nitrided samples were compared in all
tests with DLC only coated samples and the duplex ones (nitriding.
+. coating). The thickness of the nitrided layer was of 14. ¼m,
and the coating, 1.8. ¼m. The duplex samples had the best abrasive
wear resistance; their mass loss was almost negligible and within
the error of the instrument. The only coated samples had a very
low mass loss compared with the only aged steel, but the coating
was detached.The coated samples presented a low friction
coefficient, about 0.03 against alumina and the no wear loss was
detected. On the other hand, only the duplex samples presented an
acceptable adhesion in the Rockwell C indentation test with 600. N
and the critical load was 28. N in the scratch test.",
