Phase Composition of Steel-Enamel Interfaces: Effects of Chemical Pre-treatment

Popis výsledku v původním jazyce

Mossbauer spectroscopy in transmission geometry, performed simultaneously with conversion X-ray, and conversion electron Mossbauer spectroscopy, X-ray powder diffraction and electron microprobe analysis (EMPA), have been used to monitor the effects of achemical pretreatment on the phase composition of a "steel-enamel interface" of a hot-rolled steel surface formed during a thermally induced coating process. In this comparative study, we have analysed both an untreated sample and a treated sample of a steel sheet with the surface pickled by dilute H2SO4 and passivated in Na2CO3 solution. A continuous magnetite layer covering the steel surface as a result of the chemical pre-treatment was identified by backscattering Mossbauer spectroscopy and EMPA. During a fusion process, well crystalline fayalite (Fe2SiO4) is formed at the phase boundary by the solid-state reaction of magnetite with the SiO2-based enamel matrix. Wustite (FeO) was detected as a product of oxidation of iron under the m
