Nanocomposite TiSiN films were sputtered on two types of stainless steels alloys (316L and DSS2205). The corrosion properties of coated stainless steel in Hank’s solution were studied using electrochemical impedance spectroscopy and potentiodynamic measurements. in Hank’s solution, simulates the body fluid. According to electrochemical impedance and polarisation measurement, thin films increase corrosion resistance of coated substrates for 1 to 2 order of magnitude compare to the uncoated substrates.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 26341927The invention is a procedure for dynamic deep etching and particle extraction for aluminium alloys, applicable for quality control of products made of aluminium alloys, and for investigation of aluminium alloys using scanning and transmission electron microscopy, as well as Xray diffraction. The mode and sequence of individual stages of the procedure enables uniform dissolution of aluminium matrix throughout the entire volume of a specimen by using a solution composed of iodine, tartaric acid and methanol, in which the components have concentrations determined according to specimen dimensions. It is important in this regard that the solution penetrates into the interior of the specimen at specific sites only and that the surface oxide layer remains compact. An ultrasonic device is applied in the procedure, effecting the movement and penetration of the electrolyte into the interior of the specimen, and thus enhancing the dissolution process.

COBISS.SI-ID: 17122838The project coordinator Dr Darinka Kek Merl was invited by the Slovenian research agency to present key results of the project from 2011 within the scope of "Exceptional scientific achievements". The public lecture was held in March 2013 in Ljubljana, while since 2013 the video of this presentation has been available at the portal videolectures.net. In this lecture the main motivation of the project is presented, as well as key methods and first group of results. These include electrochemical characterization of the substrate materials and of diamondlike carbon coatings.
