abstract = "A duplex treatment, combining a nitriding diffusion process and
the deposition of DLC coatings is investigated as an option for
corrosion protection of precipitation hardening steels, in order
to increase the service life of components used in plastic
injection molds. Hardness and mechanical resistance are determined
and the corrosion resistance in two different media is analyzed.
Non-coated nitrided and non-nitrided samples are also tested for
comparison. Corrosion resistance is investigated by means of
immersion, salt spray, and polarization tests. No signs of
atmospheric corrosion are observed after the salt spray test and
in acid media, the nitrided samples, with and without DLC, present
the lowest mass loss. The duplex sample shows the best corrosion
behavior in the electrochemical tests. The duplex treatment
consisting in plasma nitriding and DLC deposition results in a
very good protection for PH stainless steel against wear and
corrosion. Corrosion of DLC is mostly dependent on the density of
defects that connect the electrolyte with the metal, initiating
delamination, and degradation. The nitrided layer provides in
interface which improves adhesion and retards this corrosion
process.",
