陶瓷的接合技术,如使用于宇宙联络飞船外壁耐热瓷砖的接合,已经研究和运用了各种方法。熔化陶瓷进行直接焊接,这种方法虽进行了多种试验,但是,由于没有具备高温的加热热源,所以不能实现。另外,把陶瓷作为耐热构件使用的时候,采用金属喷镀法、粘接、钎焊等方法时,由于受使用温度的制约,也不是充分的。为此,我们进行了这样的研究,即利用激光作为新的加热热源焊接陶瓷,并在实验室研究中证明这种焊接是可能的。以下介绍实验研究的结果。
Ceramic bonding techniques, such as those used in heat-resistant ceramic tiles for the outer walls of space-linked spacecraft, have been studied and applied. Melting ceramic for direct welding, although this method has been a variety of tests, but because there is no high temperature heating heat source, it can not be achieved. In addition, when ceramic is used as a heat-resistant member, the method of metal plating, adhesion, brazing, or the like is not sufficient due to the restriction of the use temperature. To this end, we conducted a study that uses lasers as the new heat source for welding ceramics and demonstrated in laboratory studies that such welding is possible. The following describes the experimental results.
