The anode layer source is a relatively poorly known technique which has so far been mainly used for etching of surfaces. In correct conditions, however, it can be also used for deposition of diamond-like carbon films. We investigated the influence of deposition parameters on the structure and composition of films. For this purpose we applied three techniques: elastic recoil deflection analysis, Rutherford backscattering spectroscopy and Raman spectroscopy. We found out that the structural ordering increases both with discharge voltage and nitrogen flow. The hydrogen concentration is about 20 at.%, it gently decreases with nitrogen flow, but does not change with other parameters.

A study of oxide layers grown on 2205 duplex stainless steel (DSS) and AISI 316L autenitic stainless steel in simulated physiological solution is presented. The oxide layers formed by electrochemical oxidation at different oxidation potentials were studied by X-ray photoelectron spectroscopy, their compositions were analysed as a function of depth. The main constituents on both the investigated materials were Cr- and Fe-oxides. The AFM topography analyses illustrated the higher corrosion resistance of the DSS 2205 compared to the AISI 316L under the chosen experimental conditions.
