Interplay between porous structure and tribo-mechanical behavior in porous Si3N4-SiC composites

Effect of filler morphology on cryogenic treatment sintered PTFE nanocomposites

Introduction. Polytetrafluoroethylene (PTFE) has outstanding chemical resistance and a low friction coefficient but weak mechanical properties and wear resistance, which restrict its wider use in tribological applications. Thus, the present study aims to investigate the coupled influence of nano-filler geometry and cry...

Durable Wear‑Resistant Epoxy Nanocomposites Reinforced with Hybrid Si3N4-Halloysite Nanofillers for Sustainable Dry‑Sliding Applications

Optimizing the Tribological Behavior of Nanocrystalline Inconel 718 by Solid Lubricant Reinforcements

Bulk metal matrix composites of nanocrystalline Inconel 718 (IN718) reinforced with various solid lubricant (SL) particles were fabricated from powder blends using a combination of colloidal mixing and high-pressure torsion (HPT). Conventional (MoS2, WS2, graphite) and modern SL (graphene nanoplatelets and functionaliz...

Microstructural and Tribological Behaviour of Ceramics Particles Reinforced Al-Matrix Composites: A Review

Natural minerals like sillimanite, zircon, rutile, ilmenite, and garnet have been found to be successful reinforcement materials for aluminium matrix composites (AMCs), providing a low-cost, thermally stable, and wear-resistant material alternative to fully synthetic ceramics like SiC, B4C, and Al2O3. This paper critic...

Mechanical properties of Zr-2.5Nb porous structures with different porosities produced by electron beam powder bed fusion.

Additive manufacturing enables the fabrication of porous metallic lattices with complex architectures. However, porous structures fabricated from conventional materials such as Ti-6Al-4V may exhibit limited ductility under certain loading conditions, motivating the exploration of alternative alloys. In this work, Zr-2....

Simultaneous high stiffness and metal-like superelasticity in TiB2–Ni coatings revealed by in-situ TEM nanoindentation

Titanium diboride (TiB2) coatings possess excellent functional and structural properties, including high hardness, good abrasion resistance, superior thermal conductivity and outstanding electrical properties. However, the intrinsic brittleness of ceramics severely restricts their application in load-bearing and impact...
