Article ID: 1003-6326(2005)06-1297-06 High temperature brazing of diamond tools YAO Zheng-jun(姚正军)1, SU Hong-hua(苏宏华)1, FU Yu-can(傅玉灿)2, XU Hong-jun(徐鸿钧)2 (1. College of Materials Science..., the brazed diamond core-drill manufactured using the new developed technique has much higher machining efficiency and much longer operating life. Key words: high temperature brazing; microanalysis......
adaptability of joint size and form, and low costs, active brazing is the best choice in ceramic/metal bonding methods. However, the study and development of high temperature active brazing filler.../metal bonding. And it has attracted extensive attention[3-5]. Amorphous alloy, a material at unsteady state, can boost atomic diffusion and surface reaction during the high temperature brazing process......
. They are attractive as structural materials for high-temperature aerospace application[1-2]. The application of C-C composites, to some extent, will be dependent on their joining technology[3-5]. Brazing...] and TiSi2[11] brazing fillers, but the heating-up temperature even reached 1 420-1 490 ℃, which would deteriorate the microstructure of superalloys. Therefore, it is necessary to develop new high-temperature......
diffusion along grain boundary from cladding to the core in annealed material will not be reduced during brazing cycle and/or in high temperature. Grain boundaries are known to contribute to faster diffusion...) in the vicinity of clad-core interface in annealed aluminum brazing sheet was investigated by EBSD technique. The results show that, with the increase of annealing temperature, the frequency of special boundaries......
can be achieved. The high temperature aluminum brazing paste mixed with minute active powders was successfully used as brazing filler metal, which can not only save raw and processed materials but also... brazing for the aluminum clustered tube of refrigerator was analyzed. According to characteristic of aluminum and aluminum alloy, a kind of high frequency power supply was devised and applied......

result shows that the heat energy produced by the coil can be made good use of and the uniformity of joint temperature is ensured if the coil plane is parallel to the pipe joint.Key words:high...Optimization design of electromagnetism induction heating technical parameters in high frequency induction brazingHE PENG(何 鹏), FENG Ji-cai(冯吉才), LIU Hui-jie(刘会杰),HAN Jie-cai(韩杰才), LIU Le-chang(刘乐昌......
be varied by changing the brazing temperature. The maximum SiC particle volume fraction of the bond material reached 37% at a brazing temperature of 500 ℃. The shear strength of the brazed bonds... with a different volume fraction of SiC particles was produced. The effect of brazing temperature on the volume fraction of SiC particles in the bond metal and the shear strength of the brazed bonds......
