Abstract
Three components of aluminum brazing were used for experiment,including Al-11Si-0.3Cu,Al-11Si-4Cu and Al-11Si-10Cu,and on the influence that the performance of brazing was by Cu content analyzed by SDTQ600 type Differential Scanning Calorimeter DSC,Phillips X'Pert type X-ray diffraction and OLYMPUS type Optical Microscope.Research showed that the basic organization was composed of matrix a (Al).eutectic silicon (a + Si) and a few primary silicon for three kinds of aluminum brazing; with the Cu elements increased,the intermetallic phase formed between Cu and Al between content increased,solder hardness increased.Melted characteristic curve of brazing showed that the content of Cu elements increased could effectively reduce the melting point of brazing,and make solidification temperature interval of brazing narrow.Corrosion test suggested that with the content of Cu increased,corrosion rate of brazing increased. Spreading area of brazing was dependent on the influence of Cu saturated degree,when Cu content was lower than its solubility in the Al.with Cu content increased,spreading area increased;conversely,the reverse.关键词
