Nanocomposite TiSiN films were sputtered on two types of stainless steels alloys (316L and DSS-2205). 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.

COBISS.SI-ID: 26341927Wear, erosion, corrosion and other forms of material deterioration lead to significant decrease of performance and thus increase the production cost. Different PVD-protective coatings have been developed in order to reduce these problems. Examples are presented from the area of biomedical applications; i.e. the stainless steel 316L substrate and stainless steel substrate protected with TiAgN and TiSiN PVD-coatings. We found that the tribo-corrosion experiments can be used to design and predict the properties of new coatings with enhanced performance and stability.

COBISS.SI-ID: 26342183Basic introduction to tribocorrosion processes is given. Tribocorrosion process is a corrosion process which results from simultanious rubbing, frettening of metals. Corrosion process is in most cases accelerated process due to removal of oxide films. For tribocorrosion study a special tribocorrosion system is needed-it consists of tribometer with specially constructed three-electrode electrochemical cell. Different setups for possible tribocorrosion study are presented as well as different electrochemical techniques that enable to study tribocorrosion processes. Different case studies are presented as well.
