Engineering Flexible Nanofibrous Hydroxyapatite Scaffolds With Tunable Degradation and Mechanical Properties for Bone Regeneration

Small, EarlyView.
Conventional hydroxyapatite ceramics are brittle and poorly resorbable, limiting their use in bone repair. To overcome these limitations, flexible scaffolds are fabricated using ceramic nanofibers as structural building blocks. Adjusting nanofiber characteristics allows modulating the mechanical properties and degradation, providing a versatile ...

Influence of Surface Roughness and Temperature on Niobium Cathodic Cage Duplex Treatment Applied to VP20TS Steel

steel research international, EarlyView.
Niobium cathodic cage duplex treatment is applied to VP20TS steel to evaluate the influence of surface roughness and temperature on coating performance. Results show that higher temperatures promote thicker nitride layers and increased microhardness, while finer surface preparation enhances adhesion and wear resistance, revealing optimal conditions for

The Influence of the Pretreatment of Tool Steel on the Running‐In Phase of Diamond‐Like Carbon Coatings

steel research international, EarlyView.
The influence of tool steel pretreatment on the running‐in behavior of TiNb‐diamond‐like carbon (DLC) coatings is investigated. Ion etching promotes carbide protrusion and increases coating roughness, while post‐deposition polishing reduces surface asperities.

Strain‐Induced NbC Precipitation as a Governing Mechanism for Hot Deformation Resistance in CrNiMnMoB Ultrahigh‐Strength Steels

steel research international, EarlyView.
Strain‐induced NbC precipitation governs hot‐deformation resistance in CrNiMnMoB ultrahigh‐strength steel by suppressing dynamic recrystallization, increasing activation energy, and refining martensitic substructures. The precipitation response is controlled by temperature, supersaturation, and strain rate, with slow deformation promoting extensive NbC

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...
