Effect of Chemical Composition of Steel on the Structure of Hot – Dip Galvanized Coating
P. Pokorny, J. Kolisko, L. Balik – Czech Technical University – Klokner Institute, Prague, Czech Republic P. Novak – University of Chemistry and Technology, Prague, Czech Republic This article describes the effect of the content of conventional steel impurity elements on the thickness and composition of the zinc layer. This article is focused primarily on low-temperature, batch hot-dip galvaniz...
متن کاملDetermination of Surface Topography and Composition of Cr-Free Pretreatment Layers on Hot Dip Galvanized Steel
Topography and composition of Cr-free, titanium-based pretreatment layers on hot dip galvanized steel were studied with scanning electron microscopy, atomic force microscopy, time of flight secondary ion mass spectrometry and Auger electron spectroscopy. A layer within the target coating weight range (4-10 mg Ti/m) for industrial coil coating processes contained a micro-structure with hillocks ...
متن کاملBond Strength of Hot – Dip Galvanized Reinforcement (b500b) with Concrete
P. Pokorný, D. Dobiáš, M. Vokáč – Czech Technical University – Klokner Institute, Prague, Czech Republic This paper evaluates the effect of initial corrosion damage to the surface of the hot dip galvanized steel coating in fresh concrete on its final bond strength. The tests were performed on uncoated and hot-dip galvanized ribbed reinforcements. The measurement of bond stress (τm) according to...
متن کاملDissolution-Induced Nanowire Synthesis on Hot-Dip Galvanized Surface in Supercritical Carbon Dioxide
In this study, we demonstrate a rapid treatment method for producing a needle-like nanowire structure on a hot-dip galvanized sheet at a temperature of 50 °C. The processing method involved only supercritical carbon dioxide and water to induce a reaction on the zinc surface, which resulted in growth of zinc hydroxycarbonate nanowires into flower-like shapes. This artificial patina nanostructure...
