Steel products are coated with Aluminum (Al) and Zinc (Zn) alloys to improve their corrosion properties. Bulk steel in batches; however, sheets by a continuous hot-dip galvanizing process. guided into out of the molten Al-Zn-Si (AZ) bath help stainless-steel rolls, known as guiding, sink rolls. These rolls subjected excessive surface AZ and, hence, replaced frequently. The deterioration immerse...

In presented work authors analyzed the high-temperature oxidation process from the point of view of its influence on effects obtained during cast iron hot-dip zinc coating. Research concerned the influence of the high-temperature oxidation, as a preliminary stage previous to coating with zinc on the change of surface layer structure as well as subsurface layer of cast iron with flake, vermicula...
