DENSITY SURFACE TENSION WETTABILITY AND ADHESIVE POWER OF LIQUID Al AND Al-RE ALLOY ON BN SURFACE
液态Al和Al-RE合金的密度、表面张力及对BN的润湿性和附着功

The density, surface tension, wettability and adhesive power of liquid high purity Al (99.999 wt-%), technical pure Al (99.6 wt-%) and Al-RE alloy on BN plate were measured using sessile drop method. The results show that both the density and surface tension gradually decrease but the adhesive power and wettability gradually increase with increasing temperature. The density increases and the shaface tension, wettability as well as adhesive power decrease with the increase of RE content respectively.
