摘要

The effect of the substrate pre-heat temperature on the dynamic wetting of galvanizing (Zn) baths on low C steel substrates was investigated. Increasing the substrate pre-heat temperature from room to bath temperature unproved the wetting. As the substrate pre-heat temperature was increased from room to bath temperature the interfacial thermal resistance was decreased by two orders of magnitude (1 X 10~(-3) to 2 X 10~(-5) m~2 K/W). The reduction in interfacial thermal resistance was related to the improvement in the initial wetting between the steel substrate and the Zn bath, which lead to increased Fe-Zn alloy layer formation.
