Abstract

Since it has been pointed out that non-wetting behavior of liquid Zn alloy sometimes occurs on high-tensile strength steels which usually contain Si and Mn, there have been a lot of studies to improve the wettability of liquid Zn. Although those studies evaluated the wettability qualitatively by observation of the surface of galvanized steels or exfoliation test of Zn with substrate steels and so on, it is further required to evaluate the wettability of liquid Zn with steels by measuring contact angle, work of adhesion, spreading velocity etc. which are usually used to assessment of general wetting behavior. In the present work, we applied a sessile drop method to measure the change in contact angle and diameter of liquid Zn droplet wetted on steels containing Si and Mn with time to evaluate quantitatively the dynamic wetting behavior of liquid Zn with those steels.
