Abstract
The joining process of SiCp/A356 composites is investigated. The two substrates are heated up to the melt temperature of Zn27Al filler metal by a resistance heating plate. At the time, a stirrer is introduced into the liquid weld seam in order to mix filler metal and two sides of substrates into a single uniform joint. After stirring, specimens are sectioned for the analysis of macro- and micro-structures along the weld region. The research shows that two typical joint interfaces with oxide film and without one were found. So, oxide film on the substrate wasn’t completely disrupted during stirring brazing at 500°C.And, the tensile strength of joint is only 50MPa.
