Synthesis of Cobalt Boride Nanoparticles Using RF Thermal Plasma

open access: yesAdvanced Powder Technology, 2014
Nanosize cobalt boride particles were synthesized from the vapor phase using a 30 kW–4 MHz radio frequency (RF) thermal plasma. Cobalt and boron powder mixtures used as precursors in different composition and feed rate were evaporated immediately in the ...

Simulating the Solidification of Boride–Boride Eutectics

Powder Metallurgy and Metal Ceramics, 2017
Computer simulations of structurization in boride–boride ceramics are performed using the standard version of phase-field theory. The simulations reproduce the main properties of eutectic structures observed in experiments, i.e., spatial segregation of components, structure formation from an overcooled melt, and complete decomposition of the system ...

Stability of Hyperlithiated Borides

The Journal of Physical Chemistry A, 1999
Structures and energetics of BLin (n = 4−8) clusters are predicted using the SCF, MP2, and B3LYP methods with the 6-31G(d) basis set, including energy evaluations at G2MP2. Cohesive energies, defined as the enthalpies of the BLin → B + Lin reactions, and Li and Li2 elimination reaction enthalpies are also estimated at B3LYP.

Vacuum boriding of austenitic steel and the structure of the boride layer

Metal Science and Heat Treatment, 1975
1. Vacuum boriding of steel Kh18N10T in amorphous boron powder at 900–1000° leads to formation of a diffusion zone on the surface that consists of borides of the (Fe, Cr, Ni)2B and (Fe, Cr, Ni)B types, and austenite and ferrite. 2. With vacuum boriding of steel Kh18N10T at 900–1000° in powdered amorphous boron the boron diffuses ...

Borides and boranes

Journal of the Less Common Metals, 1981
Abstract Structural comparisons between the higher borides and the boranes, carboranes and metallo derivatives suggest that there may be new borane structures. Also, if lower temperature, very high pressure synthetic conditions are tried, we may find three-dimensional boride-like structures containing other polyhedra and their fragments, particularly

A kinetic model for the borided layers by the paste-boriding process

Applied Surface Science, 2004
Abstract This work is dedicated to the study of the growth kinetics of the borided layers obtained by the paste-boriding process. A diffusion model based on Fick’s laws and coupled with a thermodynamic description of the Fe–B binary system was suggested to simulate the growth kinetics of the borided layers consisting only of Fe2B phase and ...
