چکیده
A top DLC film was deposited on the surface of Cr3C2-NiCr coated 38CrMoAl steel substrate, and effect cermet interlayer thickness mechanical tribological properties duplex coating investigated by experimental analysis finite element modeling (FEM). Results shown that, compared with single film, load-bearing capacity performance DLC/Cr3C2-NiCr were significantly improved, especially its anti-wear nearly ten times higher than that film. Moreover, an optimum 100 μm showed best comprehensive performance. FEM also presence limited stress concentration area within interlayer, which made far away from interface thus improved durability. What's more, increase resulted in contact increase, contributed to improvement

Nickel chromium (NiCr) powders with different titanium diboride (TiB2) additions (20, 40 and 60 wt %) were prepared with a mechanical alloying method and then sprayed using an air plasma spraying technology. The microstructure and phase composite of the powders and the cross-sections of deposited coatings were analyzed with a scanning electronic microscope and X-ray diffraction. The tribologica...
متن کاملTribological Behavior and Mechanical Properties of Graphene/PEEK Composites
PEEK has been implemented in various orthopaedic applications due to its many beneficial mechanical, tribological, and radiolucent properties. These properties can be further tailored by introducing fillers into the PEEK matrix. In this work, graphene has been incorporated due to its high mechanical resistance, intrinsic stiffness, and lubricating properties [2].
