Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Dynamic Testing of Cold Gas Sprayed Bipolar Plates–Porous Transport Layer Coating System in Proton Exchange Membrane Water Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
Through direct application of porous transport layer (PTL) on the bipolar plate (BPP) with thermal spraying, the interfacial contact resistance is improved. With the cold gas sprayed BPP–PTL coating system, a proton exchange membrane water electrolysis cell with a cell voltage of Ucell = 1.9 V can be operated up to i = 2.5 A/cm2 in a dynamic mode ...

Raman Spectroscopic Identification of Oxide Phases in a Corroded MgO–Steel Composite Anode Used in Aluminum Molten Salt Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.

Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

open access: yesAdvanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.
