SURFACE BASE EFFECTS ON ZINC COATING CHARACTERISTICS

Galvanic zinc coating applied in addition to perform appropriate performances of the base material surface such as corrosion resistance, chemical stability, required aesthetic impression etc. Galvanic zinc coating examinations are focused mostly on Zn connection with the base material, while we have poor data about the influence of the surface on the characteristics of the coating. Previous final processing has a large impact on the physical and mechanical properties and coating structure. This paper presents the results of research on the properties of zinc coatings deposition on the surface obtained by various final processing with different hardness and topography.
