液态铝在莫来石陶瓷表面润湿的研究

A Study of Wetting Mullite Ceramics with Aluminium

采用表面活性剂来处理莫来石陶瓷表面可以降低液态铝在陶瓷表面上的接触角θ．由θ＞９０°转为θ＜９０°，导致液态铝对陶瓷表面的润湿。

The contact between aluminium and mullite ceramics may be reduced by treating mullite ceramics with surfactant.The wetting of ceramics with alumimium can be done by transforming contact angle from θ>90°into θ<90°.
