  - Crystals - Rok 2019

  Single crystals of the new Ga-rich phases ReGa~5(Sn), ReGa~5(Pb) and ReGa~5(Bi) were successfully obtained from the flux method. The new tetragonal phases crystallize in the space group P4/mnc (No. 128) with vertex-sharing capped Re2@Ga14 oblong chains. Vacancies were discovered on the Ga4 and Ga5 sites, which can be understood as the direct inclusion of elemental Sn, Pb and Bi into the structure. Heat capacity measurements were...

  Przedstawiono wyniki badań powłoki kompozytowej otrzymanej przez osadzanie katodowe galwaniczne w roztworze zawierającym sole niklu, żelaza oraz cząstki ceramiki Al2O3 o różnej wielkości i stężeniu. Wykazano, że charakterystyka ceramiki posiada wpływ na szybkość korozji i zużycia ściernego. W szczególności, zawartość ceramiki wpływa dodatnio na odporność na zużycie ścierne, ale nieco obniża odporność na zużycie korozyjne.
