Abstract. The results of study on hydrogen and deuterium trapping and retention in MPG-8 grade graphite and boron carbide coating under consecutive irradiation by deuterium and hydrogen plasma in varying hydrogen irradiation conditions are presented in this paper. It is shown that deuterium content decreases both in graphite and boron carbide under irradiation by hydrogen plasma. It is also shown that the main mechanism of deuterium removal is sputtering for graphite, and isotope exchange for boron carbide.

“…In this paper, we emphasized the properties of B 4 C as a potential candidate for fusion-type reactor material [ 32 ]. That is, we are launching a preparatory study on the possible participation of B 4 C material as one of the materials that can be used as the first wall blanket and diverter in International Thermonuclear Experimental Reactor (ITER) [ 33 , 34 ]. The aim of this paper is to determine the possible defects that will form in B 4 C when irradiated with ions and neutrons and to predict the evolution of those defects [ 35 ].…”

In the presented work, B4C was irradiated with xenon swift heavy ions at the energy of 167 MeV. The irradiation of the substrate was done at room temperature to a fluence of 3.83 × 1014 ion/cm2. The samples were then analyzed with the X-ray diffraction technique to study the structural modification, as it can probe the region of penetration of xenon atoms due to the low atomic number of the two elements involved in the material under study. The nano-cluster formation under ion irradiation was observed. Positron lifetime (PLT) calculations of the secondary point defects forming nanoclusters and introduced into the B4C substrate by hydrogen and helium implantation were also carried out with the Multigrid instead of the K-spAce (MIKA) simulation package. The X-ray diffraction results confirmed that the sample was B4C and it had a rhombohedral crystal structure. The X-ray diffraction indicated an increase in the lattice parameter due to the Swift heavy ion (SHI) irradiation. In B12-CCC, the difference between τ with the saturation of H or He in the defect is nearly 20 ps. Under the same conditions with B11C-CBC, there is approximately twice the value for the same deviation.

“…Boron carbide (B 4 C) particles can be considered as an innovation filler for waterborne coatings to improve abrasion and hardness performance, 10 because of its high melting point (2450°C), high elastic modulus (450 GPa), ultrahigh hardness and relatively low density (2.52 g/cm 3 ) 11–13 . At the time writing, the most important issue of B 4 C is how to evenly disperse it in waterborne coatings.…”

In this study, waterborne polyurethane (WPU) coatings were modified by adding various compositions of nano‐boron carbide (nano‐B4C) particles. In order to achieve proper dispersion of nano‐B4C in WPU and increasing chemical interactions between them, the nano‐B4C particles were treated with polyethylene glycol (PEG) or polypropylene glycol (PPG). The modified surface and microstructure of nano‐B4C were characterized by Fourier transform infrared, scanning electron microscopy and transmission electron microscopy. The deposition experiment was designed to evaluate the dispersion effect of nano‐B4C in PEG or PPG aqueous solution. The physical performance of nano‐B4C modified WPU coatings was measured following the national standards of paints and vanishes. The results revealed that the PEG6000 not only enhanced the interaction between nano‐B4C and WPU but also exhibited a remarkable ability to improve the physical performance of WPU coating. The coating with 15 wt% of nano‐B4C addition exhibited the best performance in terms of abrasion and hardness, which could be attributed to the best uniform dispersion of nano‐B4C particles in PEG6000 aqueous solution.
