| Abstract | ||
| 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. | ||
