Abstract
In this study, the wettability of B4C by molten Al, as well as Al–Ti alloys, with different Ti contents has been studied using the sessile-drop method. In general, the contact angle decreases with increasing temperature and time. The results show that an appropriate amount of Ti addition improves the wettability of B4C by Al. Analyses of the interfaces of solidified drops revealed that Al3BC and AlB2 particles form around the B4C particles when they are in contact with pure Al. However, when Ti is added to Al, AlB2 particles disappear and a new Ti-rich layer composed of TiB2 particles forms around B4C surfaces. In addition, the effect of Ti addition on the surface tension of aluminum has also been examined.
