摘　　要：用PbO-SiO2-Al2O3系复合片状玻璃钎料,在大气环境下实现SiCp/6063Al复合材料与DM305电子玻璃的连接。用XRD、SEM、EDS和DSC等研究不同保温时间和温度下对焊接接头的影响。结果表明:在一定范围内焊接温度升高和保温时间延长可提高接头强度。SiCp/6063Al复合材料与DM305电子玻璃在钎焊温度为480℃保温30 min时,获得最大剪切强度为7.16 MPa的接头,且满足气密性使用要求。钎焊过程中,钎料中的元素能扩散到母材中,提高接头强度。PbO-SiO2-Al2O3 composite flake glass solder was used to achieve SiCp/6063 Al composites and DM305 electronic glass in atmospheric environment.The effects of holding time and temperature on the brazed joints were studied by XRD,SEM,EDS and DSC,etc.The results show that the increase of welding temperature and holding time can improve the joint strength within a certain range.The joint of SiCp/6063 Al composite and DM305 electronic glass with the maximum shear strength of 7.16 MPa can be obtained at 480℃for 30 min,which can meet the requirements of air tightness.In the brazing process,the elements in the solder can diffuse into the base metal,so as to improve the joint strength.
