Influence of chloride ions on various corrosion resistance of Zinc coating

Abstract

 Corrosion is one of the major causes for global crisis concerning the loss of materials resources and energy. It is also the cause of significant economical loss in many countries. Certain measures can be taken to minimize this problem, which is the first and foremost goal of this research work. The objectives of this study are to investigate respective aspects of chloride ions influence on various galvanic properties of zinc coating. Those included: corrosion resistance properties, the effects different concentrations of chloride solutions thereon, also the properties of galvanically deposited zinc in a variety of coating thicknesses with respect to corrosion resistance of galvanically deposited zinc in chloride solutions and the influence of chloride ions on the zinc coating given by different technologies, as warm and galvanic processes, analysis of their properties on corrosion resistance. All tests were performed with potentiostat/galvanostat Model 263A, guided by potentiodynamic polarization and linear polarization method. Based on the results presented in this research work, it is concluded that despite the costs the corrosion protection is the most effective way to prevent material loss.
