碩士 === 國立雲林科技大學 === 機械工程系碩士班 === 100 === In this study, use of mechanical agitation under sonication in the atmospheric environment using Sn-8Zn-3Bi-4Ti-0.1Mm, Sn-8Zn-3In-4Ti-0.1Mm active alloy filler bonding of 7075 aluminum alloy and Al2O3, the SUS 304 stainless steel, copper metal. Electron microprobe microscopy analysis of the bonding interface metallographic microstructure and elemental distribution in the case. Shear strength tests using the tensile testing machine and two joints on the strength of the fastener, and observe the test specimen fracture surface morphology. Sn-8Zn-3Bi-4Ti-0.1Mm and Sn-8Zn-3In-4Ti-0.1Mm complete wetting of the 7075 aluminum alloy, Al2O3, SUS304 stainless steel, copper metal surface, the specimen binding are excellent. Sonication that combine high-speed shock due to ultrasonic cavitation, make it easier for the filler alloy wetting the substrate surface to achieve better joint strength, the sonication joint rapid bonding speed, response timeliness short, compared to bonding, mechanical agitation and less likely to produce intermetallic compounds, so the average shear strength are superior to mechanical mixing junction.
