Wettability of Al2O3 by Aluminum and Al-Mg Alloys

Engineering and Technology Journal, 2010, Volume 28, Issue 9, Pages 1771-1777

The wettablity at a liquid of pure-Al or Al-Mg alloys/ Al2O3 interface was
evaluated by the sessile drop method at 700oC and with a vacuum pressure of
10-4Pa. The value of contact angle varies (decreases) with time of contact with
Al2O3 substrate. The reduction in θ of the Al-Mg alloy was proportional to the
reduction in surface tension γlv of Al, and to reactions that took place at the Alalloy/
Al2O3 interface.
