| 摘 要： | 试验采用按一定配比混合的铼、钛等金属粉末作为复合中间层材料，利用开发的电子柬扫描控制系统，通过电子束束流大小、扫描轨迹形状、扫描点数、扫描频率和加热时间等因素的调节，控制电子束输入能量的分布，从而控制基体材料对中间层的稀释率，最终达到控制中间层成分的目的．试验结果表明，用受控电子束熔炼粉末金属可以获得满意的中间层材料．

| Abstract: | A few kinds of metal powder such as Re,Ti mixed in a certain element proportion are selected as a composite interlayer in the investigation.The electron beam(EB) input energy distribution can be effectively controlled by adjusting the beam current magnitude,shape of scanning track,scanning point numbers,scanning frequency,heating time and so on.As a result,the dilution rate that the interlayer is diluted by the Ti base material can be controlled,that is,the composition of the interlayer metal can be controlled.The experimental results indicate that the powder fusion metallurgy with the controlled EB can achieve the approved interlayer. |
