Effect of the Surface Oxidation on the Hot-dip Zinc Galvanizing of Cast Iron Wpływ Powierzchniowego Utleniania Na Efekty Cynkowania Ogniowego Żeliwa

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...

REACTION KINETICS OF THE FORMATION OF INTERMETALLIC Fe – Zn DURING HOT - DIP GALVANIZING OF STEEL

P. Pokorny, J. Kolisko, L. Balik – Czech Technical University – Klokner Institute, Prague, Czech Republic P. Novak – Institute of Chemical Technology, Prague, Czech Republic This review article mainly describes the composition of intermetallic Fe Zn, i.e. zeta (ζ), delta (δ1k + δ1p), gamma1 (Γ1) and gamma (Γ) on galvanized steel during low temperature galvanization (t ~ 450 °C). It gives detail...

Exploring Carbide-Free Bainitic Structures for Hot Dip Galvanizing Products

Model Checking. Part II

(Def. 1) CastNatx = { x, if x is a natural number, 0, otherwise. Let W1 be a set. A sequence of W1 is a function from N into W1. For simplicity, we use the following convention: k, n denote natural numbers, a denotes a set, D, S denote non empty sets, and p, q denote finite sequences of elements of N. Let us consider n. The functor atom. n yields a finite sequence of elements of N and is define...

Effect of Mg on the Microstructure and Corrosion Resistance of the Continuously Hot-Dip Galvanizing Zn-Mg Coating

The microstructure of continuously hot-dip galvanizing Zn-Mg coating was investigated in order to obtain the mechanism of the effects of Mg on the corrosion resistance. In this paper, the vertical section of the Zn-0.20 wt % Al-Mg ternary phase diagram near the Al-low corner was calculated. The results indicates that the phase composition of the Zn-0.20 wt % Al-Mg ternary phase diagram near the...
