Некоторые трибологические свойства Al-W-B материалов
No full textОбъектом исследования являются технологические отходы при производстве композитного материала Al-W-B, содержащего однонаправленные иглообразные боровольфрамовые волокна и алюминиевую матрицу. Потенциальные возможности применения отходов Al-W-B материала должны быть обоснованы их соответствующими свойствами.
Особый интерес представляют отходы этих материалов после их измельчения в порошок Предполагается их использование в качестве лигатуры при изготовлении некоторых сплавов. а также в качестве материалов для шлифовально – полировального инструмента. Однако пока отсутствуют данные по исследованию трибологических и абразивных свойств Al-W-B материалов. Этому направлению и посвящена данная работа

Highly Efficient Nanoflower-like Bifunctional Electrocatalyst Co-W-B-P/CF for Overall Water Splitting
No full textElectrochemical
water splitting to produce clean hydrogen (H2) and oxygen
(O2) has emerged as an advanced technology
to build a sustainable society. Low-cost electrocatalysts with excellent
performance are required to improve the energy efficiency in overall
water splitting. Here, a Co-W-B-P/CF catalyst with a nanoflower-like
structure consisting of microspheres and nanoflakes was successfully
synthesized using a one-step double-pulse electrodeposition approach.
When used as a bifunctional electrocatalyst for overall water splitting,
Co-W-B-P/CF presented the potentials of 1.57 and 1.86 V at current
densities of 10 and 100 mA cm–2 in 1.0 M KOH solution,
respectively. This was even comparable to that of the high-cost commercial
catalyst Pt/C(−)//IrO2(+). Detailed electrochemical
tests also showed that the kinetics, electron transfer, and intrinsic
electrocatalytic activity of Co-W-B-P/CF in the HER (hydrogen evolution
reaction) and the OER (oxygen evolution reaction) were dramatically
improved due to the synergetic effect of co-doped B and P elements.
Considering the excellent electrocatalytic performance of Co-W-B-P/CF,
along with the simple synthesis method and low cost, bifunctional
electrocatalyst Co-W-B-P/CF for overall water splitting is promising

Influence of Al-W-B Recycled Composite Material on the Properties of High Performance Concrete
No full textThe aim of this study is to obtain high performance
boron containing material with sufficient carrying capacity with
increased porosity and lower density at the same time. The
influence of the different concentrations of Al-W-B powder on
the properties of the fresh and hardened HPC was investigated.
In the concrete mix design, the allite containing White Portland
cement CEM I 52,5 R, granite stone, sand, microsilica, on
polycarboxylates based super plasticizer and Al-W-B powder
were used. As a source of boron composite material (CM),
previously grinded powder containing boron-tungsten fiber and
aluminium matrix (CM Al-W-B) was used. Grinding was used
for processing of CM Al-W-B powder
