摘要
将苯乙烯共聚物制备的粘结剂与镍基合金粉末混合并轧制，成功研制新型镍基粘带钎料。研究了粘结剂用量、镍基合金粉末的粒度、轧制速度等制备因素对粘带钎料的影响，使用同步热分析仪测试了镍基粘带钎料的熔化特性，分析了镍基粘带钎料的润湿铺展性能。结果表明，镍基粘带钎料厚度可控制在0．05～2．0mm范围，不同厚度的粘带钎料具有对应的最佳制备工艺参数，粘结剂在485．7～612．9℃温度区间能够分解、挥发干净，粘带钎料具有优异的润湿铺展性能，熔化后无残留。
The mixture of nickel-based alloy powder and binder,which was produced from styrene copolymer,was rolled. Then the new type of nickel-base adhesive brazing tape was made successfully. The effect of binder dosage,nickel-base alloy powder granularity and rolling speed on brazing tape was studied. The melting characteristics of nickel-base adhesive brazing tape was tested by simultaneous thermal analyzer. The wettability and spreadability of nickel-based adhesive brazing tape were analyzed. The results showed that the thickness of nickel-base adhesive brazing tape can be controlled in 0. 05 ~ 2. 0 mm,and the brazing tapes at different thickness was in accordance with the optimum preparation parameters. The binder was decomposed and evaporated completely in 485. 7 ~ 612. 9 ℃. The brazing tape has excellent wettability and spreadability,and no residue existes after melting.
