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

Advanced 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

Advanced 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 ...

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

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

Advanced 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.

Experimental Induction Heating Hypophysectomy

Stereotactic and Functional Neurosurgery, 1973
The use of implanted metal seeds to induce hypophysectomy using induction heating was studied <i>in vitro</i> and in experimental animals. The preliminary observations indicate that this technique is not satisfactory for bringing about total hypophysectomy at primary operation but may be useful in permitting secondary lesions in the ...

Transverse flux induction heating

Electrical Engineering, 1950
FOR SEVERAL years following 1941, the author was engaged in the development of radio-frequency induction heating for the flow-brightening of electrolytic tin plate. Lines are in operation today melting the electrolytically deposited tin coating on 30-inch-wide steel strip at speeds of 1,300 feet per minute with a power input of 1,200 kw to the strip ...

Induction and Dielectric Heating

Transactions of the American Institute of Electrical Engineers, 1948
Induction and dielectric heating have assumed in recent years an important position in industrial heating; dielectric heating more recently than induction. These unique forms of heating, once responsible only for power losses in electric equipment and machinery, offer many advantages over conventional means of heating by convection, conduction, and ...

Induction Heating Sintering

2018
In this chapter, the principle of induction heating sintering and the features of the microstructure development of induction sintered materials are presented. Direct induction heating can only be realized in conductive materials and is caused by eddy currents created by an alternating magnetic field.

Surface heating by induction

Electrical Engineering, 1944
Induction heating offers a method for heating of electrical conductors such as steel, brass, graphite, by exposing them to a varying magnetic field. The application of induction heating to melting, forging, surface hardening, and other uses is becoming increasingly common, resulting in a mounting interest for a physical concept of the heating effect ...
