| 摘 要： | 热扩散法是制取部分合金化Ｃｕ－Ｓｎ粉末的途径之一，作者研究了扩散温度对Ｃｕ－Ｓｎ粉末压制与烧结性能的影响，实验结果表明，Ｃｕ－Ｓｎ粉末的压实性及烧结胀大现象，都随着扩散温度的提高而降低，Ｃｕ粉颗粒越粗，获得具有相同烧结性能的Ｃｕ－Ｓｎ粉末的扩散温度越高。

| Abstract: | The mixtures of copper powder and tin powder show large dirnensional change duringsintering-sintering expansion which makes control of the final dimensions difflcult.The de-gree of sintering expansion can be reduced by using partially alloyed Cu-Sn powder.Therrnaldiffusion is one,of the methods of producing partially alloyed Cu-Sn powder.The effect ofdiffusion temperature on compressihility and sinterability of Cu-Sn powder was studied.Theexperimental results indicate that the compressibilily and sintering expansion of Cu-Sn pow-der decrease with the raising diffusion temperature.The coarser the copper particle and thehigher the green density of compact,the higher the diffusion temperature to obtain the Cu-Sn powder possessing the same sinterability. |
