Sažetak
Surface engineering includes many different processes for modifying and coating surfaces of tools and structural parts in order to adapt them to specific exploitation requirements. Improving the properties of materials by such processes primarily implies reducing degradation caused by wear or unwanted corrosion processes, and ultimately with the aim of extending the tool life under certain operating conditions. In this paper, preliminary investigations of material properties were performed using the recently developed non- destructive method of electrochemical impedance spectroscopy (EIS) on test specimens of two structural steels coated by hard chromium plating, chemical nickel plating and plasma-assisted chemical vapour deposition (PACVD) layers. The method measures the complex resistance spectrum in a wide frequency range of the input AC signal, which enables a detailed analysis of the examined coating-substrate systems. The conducted examination monitored changes in resistance on undamaged and damaged layers in order to understand the possibility of applying the EIS method for detecting damage to protective coatings.
