Mesoporous fibrous silicon nitride by catalytic nitridation of silicon
Progress in Natural Science: Materials International, 2019 [EN] The catalytic effect of metal oxide/alumina whiskers (CeO2,Mn3O4, NiO, Co3O4,Fe2O3,Cr2O3/AW) was eval-uated on their ability to drive the nitridation of silicon and to generate mesoporousfibrous silicon networks.Silicon powder with different particles size along with the catalyst was nitridized at 1300 °C for 5 h in nitrogenand nitrogen diluted ...

Silicon Nitride Bearings for Total Joint Arthroplasty
Lubricants, 2016 The articulation performance of silicon nitride against conventional and highly cross-linked polyethylene, as well as for self-mated silicon nitride bearings, was examined in a series of standard hip simulation studies. Wear rates for polyethylene liners

Advanced Engineering Materials, EarlyView.The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

A feature extraction method for silicon nitride bearing microcracks based on adaptive gamma and multi-width dynamic thresholds [PDF]
AIP AdvancesThis study aims to address the problems of localized indistinctness, low contrast, and unclear feature recognition in images of silicon nitride bearing surfaces by proposing adaptive gamma variation and multi-breadth dynamic threshold segmentation ...

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.
