Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Bioinspired 3D‐Printed NiTi Metamaterials With Bivalve‐Like Crossed‐Lamellar Structures
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metamaterials demonstrate unique mechanical properties and functional performance owing to their distinctive topological spatial structures. In this study, by mimicking the natural Saxidomus purpuratus shell, bioinspired crossed‐lamellar architectures with interlamellar apex angles ranging from 60° to 150° were designed and fabricated in NiTi ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...
