Controlling Carbon Migration and TiC Formation in Roll-Bonded Ti-6Al-4V/440C Stainless Steel Composites through Interlayer Design

Interfacial Reaction Products and Mn/Mo-Regulated TiC(001)/γ-Fe(001) Interfaces in Titanium–Steel Clad Plates: A First-Principles Investigation

: Titanium–steel clad plates combine the corrosion resistance of titanium alloys with the strength and cost advantages of stainless steels, making them attractive for advanced structural applications. However, interfacial reactions during fabrication or service may lead to the formation of Fe–Ti intermetallic compounds...

High-temperature corrosion of Ti6Al4V and in-situ reinforced composites fabricated by laser additive manufacturing

This study investigates the high-temperature corrosion behaviour of directed energy deposited (DED) Ti6Al4V (Ti64) and its in-situ composites (TiC/Ti64 and TiBw/Ti64) in oxygen-rich NaCl- Na 2 SO 4 environments at 300 °C, 600 °C, and 900 °C. DED produces refined microstructures with reinforcement phases distrib...

Mechanistic study on the influence of semi-solid processing on the interfacial bonding performance of copper-steel bimetallic composites

Copper-steel bimetallic composites combine the high thermal and electrical conductivity of copper with the strength and wear resistance of steel, yet their performance and service life remain constrained by interfacial bonding quality. Although semi-solid processing offers a promising route to interface optimization, i...

Microstructural Characterization and High-Temperature Oxidation Behavior of NiCrAlY/YSZ Coating on 20G Steel

To improve the high-temperature oxidation resistance of 20G steel, NiCrAlY and yttria-stabilized zirconia (YSZ) coatings were deposited via plasma spraying. Subsequently, high-temperature cyclic oxidation analysis was performed at 900 °C for a total duration of 80 h (10 cycles) to examine the oxidation kinetics of 20G...

Interface-Controlled Phase Transformation and Corrosion Performance of Nb/NbN Multilayer Coatings for Bipolar Plates.

Proton exchange membrane water electrolysis (PEMWE) bipolar plates face a critical trade-off between corrosion resistance and interfacial electrical conductivity. To address this, Nb/NbN multilayer coatings with systematically varied interface densities were deposited on TA1 substrates via magnetron sputtering. Increas...
