采用接触反应钎焊实现了复合电热餐具铝热管与铝板以及铝板与不锈钢板结构的高致密连接。通过选择接触反应钎焊的中间层成分 ,采用Si为中间层介质进行钎焊工艺试验。对接头组织的显微分析表明 ,Si中间层介质与铝基体之间发生共晶反应所产生的Al Si共晶液相 ,能够将铝加热管与铝板以及铝板与不锈钢板大面积结构致密地连接在一起。 Adopt contact reaction brazing to realize the high density connection of aluminum heat pipe and aluminum plate as well as aluminum plate and stainless steel plate structure of the composite electric tableware. By selecting the contact brazing intermediate layer composition, using Si as the intermediate layer medium brazing process test. Microstructure analysis of the joint shows that the Al Si eutectic liquid phase produced by the eutectic reaction between the Si intermediate layer medium and the aluminum matrix can connect the aluminum heating tube to the aluminum plate and the large-area structure of the aluminum plate and the stainless steel plate densely Together
