    Opis:
    Reactive magnetron sputtering of austenitic stainless steel in nitrogen containing atmosphere was used to deposit coatings composed of S-phase. The process was conducted at constant temperature (200°C). The influence of total and partial nitrogen pressure on coating characteristics was investigated. It was observed that both total and nitrogen partial pressures have influence on coating composition and microstructure. Increasing nitrogen content in the S-phase coating can have a beneficial effect on its corrosion characteristics. It was also found that coatings deposited in the ambient of high nitrogen contents are composed of S-phase and the additional high-nitrogen phase, which is of crucial influence on mechanical properties of the coatings. It was also found that partial argon pressure can contribute to the changes in mechanical properties of the coatings.

    Opis:
    The paper presents the results of investigations of carbon doped austenitic stainless steel coatings (carbon S-phase) obtained by the reactive magnetron sputtering in the reactive atmosphere composed of argon and methane as a carbon source. Stainless steel targets were sputtered under different conditions. During the experiments the argon to methane proportion varied within a range 11/2-7/6. The other parameters such as temperature, pressure, sputtering power, etc. were kept constant. The phase composition was determined using the X-ray diffraction. Electron probe microanalysis (energy dispersive spectroscopy and wavelength dispersive spectroscopy) and glow discharge optical emission spectrometry techniques were used to study element composition of the coatings. Microstructure was investigated by scanning electron microscopy. It was found that varying the methane volume in the reactive atmosphere, it is possible to control the lattice parameter of the carbon S-phase.

    Opis:
    In this paper the physical properties of two types of Co-doped ZnO nanostructures: tetrapods and nanofibers grown by a rapid thermal evaporation process and prepared by the electrospinning technique, respectively, were investigated and analyzed. Surface morphology of the samples was examined using scanning electron microscopy. X-ray diffraction measurements showed hexagonal wurtzite crystal structure of both types of investigated nanostructures. Both X-ray diffraction and Raman scattering data confirmed high phase purity of the samples. The magnetic properties studied with the use of the SQUID magnetometer confirmed a presence of ferromagnetic order in analyzed nanostructures. The observed photoluminescence spectra exhibited two groups of lines. The first one, in the ultraviolet spectral range, is due to the optical transitions close to ZnO band gap, the second one in the red region is most probably related to the $Co^{2+}$ d-d internal transitions. The influence of native defects on the optical properties is also shown and discussed. All results reported here lead us to the conclusion that in the mixed crystal nanostructures obtained, a fraction of the $Zn^{2+}$ ions is substituted by $Co^{2+}$ ions.
