    • Complex frictional analysis of self-lubricant W-S-C/Cr coating 

      Autor: Polcar, Tomáš; Gustavsson, Fredrik; Thersleff, Thomas; Jacobson, Staffan; Cavaleiro, A.
      (Royal Society of Chemistry, 2012)
      Transition metal dichalcogenides belong to one of the most developed classes of materials for solid lubrication. However, one of the main drawbacks of most of the self-lubricating coatings is their low load-bearing capacity, ...

    • Microstructural investigation on the grain refinement occurring in Cu-doped Ni-Ti thin films 

      Autor: Callisti, M.; Mellor, B.G.; Polcar, T.
      (Elsevier, 2014)
      The mechanism of grain refinement in Cu-doped Ni-Ti thin films have been investigated by transmission electron microscopy (TEM). Sputter deposited (Ni,Cu)-rich Ni-Ti-Cu thin films exhibited a columnar structure consisting ...

    • Nanoscale colour control: W–O graded coatings deposited by magnetron sputtering 

      Autor: Polcar, T.; Kubart, T.; Malainho, E.; Vasilevskiy, M.; Parreira, N.M.G.; Cavaleiro, A.
      (IOP Publishing, 2008)
      A new design of decorative tungsten oxide coatings is presented. The coatings were deposited with gradient refraction index by magnetron sputtering from a tungsten target and pulsing the reactive gas. The controlled injection ...
