Ein Verfahren zur Ermittlung der Rissentwicklung während des Feuerverzinkens

Hot‐dip galvanizing represents a very effective method to protect components against corrosion. During the hot‐dip galvanizing process, however, there is a risk that cracks form in the component. With an increase of the temperature of the zinc bath, the danger of crack formation also increases. This article describes a method to determine the start of the crack formation during hot‐dip galvanizing. With a few tests, this method allows to determine a stress‐strain limit (energy limit) below which no liquid metal assisted cracking (flüssigmetallinduzierte Rissbildung) can occur during the transient phase of hot‐dip galvanizing.
