介绍了液态铝的润湿性测量原理,并采用改进的座滴法装置测定了纯铝和Al-0.5%La合金在Al_2O_3表面的润湿性.结果表明,少量稀土元素的加入可以改善铝对Al_2O_3的润湿性.使其润湿角从90.5°减小到80.0°.
The principle of measuring the wettability of liquid aluminum was introduced and the wettability of pure aluminum and Al-0.5% La alloy on the surface of Al_2O_3 was measured by the improved droplet method.The results show that the addition of a small amount of rare earth elements can improve the aluminum- Al 2 O 3 wettability, reducing the wetting angle from 90.5 ° to 80.0 °.
