Magnesium when hydrided has low thermal and electrical conductivity and carbon coating would be useful to remedy this for a variety of purposes. In this study, carbon coating was achieved by co-feeding magnesium and methane into a thermal plasma reactor. This yielded carbonaceous material with magnesium particles 5-10 nm in size embedded in graphitic matrix. A further reduction down to 2-3 nm was possible but required reductions in the precursor feed rate. 2 wt% carbon was sufficient to fully protect magnesium particles of approx. 260 nm in size. Light milling, however, disrupts the continuity of graphitic envelop and the particles then react both with oxygen and hydrogen.

Nanomaterial-Enhanced All-Solid Flexible Zinc-Carbon Batteries
Hiralal, Pritesh; Imaizumi, Shinji; Ünalan, Hüsnü Emrah; Matsumoto, Hidetoshi; Minagawa, Mie; Rouvala, Markku; Tanioka, Akihiko; Amaratunga, Gehan A. J. (2010-05-01)
Solid-state and flexible zinc carbon (or Leclanche) batteries are fabricated using a combination of functional nanostructured materials for optimum performance. Flexible carbon nanofiber mats obtained by electrospinning are used as a current collector and cathode support for the batteries. The cathode layer consists of manganese oxide particles combined with single-walled carbon nanotubes for improved conductivity. A polyethylene oxide layer containing titanium oxide nanoparticles forms the electrolyte laye...
Carbon Coating of magnesium via thermal plasma
Aktekin, Burak; Eyövge, Cavit; Öztürk, Tayfur (null; 2018-05-07)
Magnesium is a material of considerable interest for electrochemical as well as thermal energy storage. Carbon coated magnesium or magnesium nanopartciles emebedded in a graphitic matrix could provide solutions to some of the problems currently faced in these application areas. The current study was undertaken to develop Mg-C composites at a variety of length scales. The synthesis was achieved by co-feeding magnesium and methane into an RF thermal plasma reactor. This yielded carbonaceous material with magn...
Development of high temperature creep resistant aluminium based sand cast magnesium alloys
Yalınız, Emrah; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2018)
The aim of this thesis is to develop alternative sand casting aluminum based magnesium alloys to substitute current sand castable helicopter transmission housing magnesium alloys such as ZE41A and EV31A. AZ91 magnesium alloy has also been preferred for helicopter transmission housing material. However, the lower creep resistance above 120 oC due to the presence of -(Mg17Al12) phase in the microstructure and showing varying mechanical properties in different section thicknesses limit the usage of AZ91 in th...
Induction thermal plasma synthesis of Mg2Ni nanoparticles
Aktekin, Burak; ÇAKMAK, GÜLHAN; Öztürk, Tayfur (2014-06-15)
A study was carried out into possibility of thermal plasma synthesis of Mg2Ni nanoparticles. Both prealloyed powders and elemental powders were used as precursors in an inductively coupled thermal plasma incorporating two injection probes located axially in the reactor one from the top and the other from the bottom. The study has shown that the use of prealloyed Mg2Ni as precursor leads to its disintegration in the plasma condensing into separate phases and therefore was not suitable for the synthesis of Mg...
ELECTROLESS DEPOSITION OF OXIDATION RESISTANT HIGH TEMPERATURE COATINGS IN MOLTEN SALT
Ömür, İshak Emre; Karakaya, İshak; Erdoğan, Metehan; Department of Metallurgical and Materials Engineering (2021-9-10)
Molybdenum and molybdenum alloy (TZM) can be protected against oxygen in hightemperature environment by developing silicide coating on their surface without damaging their mechanical properties. In this study, molybdenum di-silicide was coated on pure molybdenum and its alloy (TZM) surfaces using a molten salt method. NaCl-KCl-NaF eutectic composition was used as salt mixture, and Na2SiF6 and silicon powder were added to the system as silicon source. X-ray diffraction (XRD), Inductively Coupled Plasma ...
