| Abstract: | Joining for the material of the bionic unsmoothed unit(white cast iron)is one of the key technology in the studies of the bionic unsmoothed surface for the reducing soil adhesion and plowing resistance.The interface features of the metallurgy action and the influence of the interface on the brazing joint mechanical property are investigated for poly copper based filler metal brazing white cast iron by using metallography?SEM?electron probe and X ray diffractometer.Interface metallurgy action is intense for copper based filler metal brazing white cast iron and the influence of the time and temperature on the interface formation is obvious.The formation of the complicated interface reduces the brazing joint shearing strength.Fracture originates from the interface of the brazing joint along copper based filler metal brazing white cast iron. |
