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...

Submersible drainage sump pumps work in a highly corrosive environment, forming films with reaction products on the surface. Pump rotors are high-demand parts, so they made of quality materials good wear and corrosion resistance properties such as nodular graphite cast iron. This paper analyses behaviour iron used manufacture three types wastewaters, variable pH. Nodular samples were immersed w...

This thesis deals with the heat evolution during solidification and its relation to the formation of porosity. It intends to improve the current understanding of the formation of porosity in cast materials with special interest in nodular cast iron and the spray forming process. Two different systems, a Fe-based alloy, Cast iron, and a Ni-based alloy, Inconel 625, are examined. The effect on th...
