钛合金的本质决定了其钎焊的主要温度/时间局限性。总的来说,使用焊料并在钎焊温度低于β相转变温度时可获得优良机械性能的钛钎焊部件。介绍了不同的钛钎焊钎料,包括低温Ag、Al基钎料和高温TiZrCuNi基钎料,并较详细地讨论了钛合金钎焊工艺的优缺点,用TiCuNi和TiCrCuNi为粉末钎料进行了各种Ti合金、TiAl合金及Ti基复合材料的钎焊试验,指出获得最佳接头性能的钛合金钎焊工艺的发展方向。
The nature of titanium determines the main temperature / time limitations of its brazing. In general, titanium brazing parts that use solder and achieve good mechanical properties when the brazing temperature is below the β-phase transition temperature are obtained. Different titanium brazing filler metals, including low-temperature Ag, Al-based brazing filler metal and high-temperature TiZrCuNi-based brazing filler metal, are introduced. The advantages and disadvantages of the brazing process of titanium alloy are discussed in detail. TiCuNi and TiCrCuNi are used as powder brazing filler metal Various types of Ti alloy, TiAl alloy and Ti-based composite brazing test, pointed out that the optimal performance of the joint titanium brazing process development.
