INVESTIGATION OF CHROMIUM AND VANADIUM CARBIDE COATING FORMATION ON SKD11 AND T10 BY THERMO-REACTIVE DIFFUSION (TRD) METHOD
Carbide coatings, due to their excellent anti-wear properties, are used to extend the life of molds exposed to abrasion forces. Various processes have been applied to produce carbide coatings. Thermo-reaction diffusion (TRD) using a molten salt bath could be considered as an economical method compared to other coating processes. In this study carbide-composite coatings using molten salt baths c...

15 صفحه اولFormation and Disruption of W-Phase in High-Entropy Alloys
High-entropy alloys (HEAs) are single-phase systems prepared from equimolar or near-equimolar concentrations of at least five principal elements. The combination of high mixing entropy, severe lattice distortion, sluggish diffusion and cocktail effect favours the formation of simple phases—usually a bcc or fcc matrix with minor inclusions of ordered binary intermetallics. HEAs have been propose...
متن کاملEncapsulation of Iron Carbide in Carbon Nanocapsules
Whiskers of iron carbide encased in carbon shells have been prepared from iron(I1) phthalocyanine. Solid FePc is oxygenated and then thermally treated under H2 flow. With proper control of conditions, Fe3C free from metallic iron can be synthesized. The product was characterized with the help of Mossbauer effect spectroscopy, X-ray diffraction, X-ray absorption, and transmission electron micros...
متن کاملSynthesis of calcium carbide-derived carbon by mechanochemical reaction of calcium carbide with sulfur, iron sulfide and zinc oxide
In the present work, we report a novel design and preparation for the mechanochemical synthesis of calcium carbide-derived carbon (CaC2-CDC) at ambient temperature. Thermodynamic calculations confirmed the possibility of calcium carbide-derived carbon formation by the reaction of calcium carbide with sulfur, iron sulfide and zinc oxide at ambient temperature. The CDCs were synthesized by the ba...
