“…2.5 illustrates the equilibrium phase diagrarns of zinc-iron and zinc-nickel binary systems. The phases found in the CUITent diagram are outlined in Table 2.2 [ Mackowiak and Short 1979, Villars and Calurt 1986, Villars and Calurt 1991. The differences in phase compositions between the equilibrium and the electrodeposited nonequilibrium states are shown in Fig.…”

“…Since the solid solubility of iron in zinc is quite minimal in the equilibrium state (less than 0.02 0/0) [Hamsen and Anderko 1958, Fujieda 1992, Porter 1991, Mackowiak 1979], the iron oversaturated 11 phase is a metastable phase formed under non-equilibrium conditions during the electrodeposition process.…”

The feasibility of iron-zinc intermetallic-phase preparation by spark-plasma sintering (SPS) was investigated. The samples were prepared with a combination of powder metallurgy, where the powder was prepared in evacuated quartz tubes, and a sintering process using SPS. Since the Fe-Zn intermetallic phases are mostly used for hot-dip galvanized steels, the knowledge of the properties of individual intermetallic phases is vital for a better understanding and even further optimization of galvanization processes. The main aim of the article is to compare the phase composition of the initial powder with the SPS samples using X-ray diffraction. Furthermore, the hardness and microstructure were investigated as well. Keywords: Fe-Zn intermetallics, spark-plasma sintering, diffusion annealing, phase composition, hardness Preu~evana je bila izvedljivost priprave`elezo-cink intermetalnih faz s sintranjem v iskre~i plazmi (SPS). Vzorci so bili pripravljeni s pomo~jo metalurgije prahov, kjer so bili prahovi zaprti v evakuirane kvar~ne cevi, ki mu je sledil postopek SPS. Ker se Fe-Zn intermetalne faze ve~inoma uporablja pri vro~em cinkanju jekel, so lastnosti posamezne faze pomembne za bolj{e razumevanje in celo za optimiranje procesa galvanizacije. Glavni namen~lanka je primerjava sestave faz s pomo~jo rentgenske difrakcije v za~etnih prahovih in SPS vzorcih. Preiskovani sta bili tudi trdota in mikrostruktura. Klju~ne besede: Fe-Zn intermetalne zlitine, sintranje z iskre~o plazmo, difuzijsko`arjenje, sestava faz, trdota

Two different steel substrates are applied to the hot dip (Zn) -coating formation. The influence of the substrate composition on the (Zn) -coating thickening is recorded. Morphologies of both coatings are compared to each other. The transition from stable into meta-stable solidification is revealed. The criterion for the competition between stable and meta-stable solidification is applied to justify the analyzed transition.Keywords: (Zn) -coatings; Fe-Zn phase diagrams; growth kinetics; kinetics law Zastosowano dwie różne stale jako podłoża dla uzyskania dwu zróżnicowanych powłok (Zn). Dokonano porównania wpływu składu obydwu rodzajów podłoża na kinetykę wzrostu powłok (Zn). Dokonano zestawienia morfologii obydwu powłok. Ujawnione zostało przejście od krystalizacji stabilnej do meta-stabilnej. Zastosowano kryterium współzawodnictwa między krystalizacją stabilną a meta-stabilną dla uzasadnienia analizowanego przejścia.
