    摘要:

    超聲波釬焊技術(shù)始于上世紀(jì)30年代末,它無需釬劑即可實(shí)現(xiàn)鋁合金、鋁基復(fù)合材料、鈦合金、陶瓷等難潤(rùn)濕材料的連接,被普遍認(rèn)為是替代釬劑釬焊最有前途的方法。釬料/母材潤(rùn)濕界面氧化膜的去除是超聲波釬焊中的一個(gè)主要問題,氧化膜的殘留將嚴(yán)重影響釬焊質(zhì)量。本文針對(duì)鋁合金表面液態(tài)釬料聲致鋪展前沿往往存在氧化膜殘留的問題,采用實(shí)驗(yàn)與模擬相結(jié)合的方法分析了氧化膜殘留的特征、原因,并提出相應(yīng)的消除措施。本文的研究工作對(duì)提高超聲波涂覆、表面金屬化以及超聲波釬焊的質(zhì)量具有重要意義。

    Abstract:

    Ultrasonic soldering technology, which commenced in the late 30s of last century, has been used to successfully join aluminum alloy, aluminum matrix composites, titanium alloy, ceramics and other hard to wetting materials without the assistance of flux. It is widely regarded as the most promising alternative to the flux-assisted soldering. Removing the oxide film at the interface of solder/base material is one of the most important problems for the ultrasonic soldering process. In the light of the presence of residual oxide film at the frontier of acoustic-induced solder spreading on the aluminum alloy, combined experimental and simulation analysis work was conducted to discover the characteristics and formation of the residual oxide film. Meanwhile, the elimination measure for the oxide residues was put forward. The results are of great significance to improve the quality of the ultrasonic-assisted coating, surface metallization and ultrasonic soldering.
