Sažetak
With introducing the environmentally acceptable fountain solution in printing systems, the effect of corrosion of machine elements becomes more aggressive, unknown and unpredictable, which partly or completely disables long-term exploitation and amortization of printing machines. In addition, the electrochemical potentiodynamic measurements were carried out with the direct current and the method of linear polarization and Tafel’s extrapolation, by which the corrosion parameters were determined: corrosion potential, corrosion current density, polarization resistance cathodic and anodic inclination of Tafel’s lines, as well as the corrosion rate. This article gives an insight into a different principle of corrosion processes in conventional and environmentally acceptable fountain solutions wetting solution, and contributes to more precise predictions of spending offset machines that use organic solvents.
