Abstract
一种用于钛蒸汽透平叶片(1)的保护端梢(5)，它的成份为：Tie20%～40%，Cr+Co12%～26%，Mo1%～6%，Ni3%～8%，CH0.3%～1.5%，其它为铁。端梢(5)被焊接到叶片(1)上，它们之间插有其厚度为7/100毫米～15/100毫米的铜带。将叶片(1)和它的端梢(5)的温度在真空或情性气体的烘箱中升高到900℃～950℃，该温度保持30～75分钟，再将烘箱温度下降到环境温度。最佳的焊接能端梢(5)硬化，使其具有非常良好的防水滴冲蚀能力。
Description
本发明涉及一种钛合金制造的透平叶片的保护端梢。
蒸汽透平的钛合金叶片用于有较大尺寸的最后的低压级特别有利，然而在上述最后级中，蒸汽中含有的水滴将碰击圆周速度很高的运动叶片。
日本专利JP59-60003公开了一种保护透平叶片前缘的方法，在叶片前缘先沉积上一种由50-90%（重量）Cu和10-50%（重量）Ni组成的金属，然后加上一抗腐蚀的保护端梢。这种保护端梢由钴基合金制成。但是钴的价格较贵，且资源较缺乏。
本发明的目的是使用一种含钴量更低的合金来制造透平叶片的保护端梢，但仍然具有好的抗腐蚀性及其它机械性能，能很好地保护透平叶片。
为了实现本发明的上述目的，本发明提供了一种钛合金透平叶片的保护端梢，该端梢的成分为：
Tic：28%～40%
Cr+Co：1%～26%
Mo：1%～6%
Ni：3%～8%
Cu：0.3%～1.3%
Fe：其他部分
钛碳化物的膨胀系数和剪切模数与钛相同，粘合剂由防腐蚀性强的钴、铬和可改善部件韧性的镍组成。
钛碳化物容易与铁的基体结合。
端梢的结构是马氏体，由于存在铬和钛，它的耐磨性强，由于存在镍，它的韧性高。
本发明的保护端梢可用下面方法焊到叶片上：
端梢放置在叶片上，并在它们之间插入一个厚度为7/100毫米～15/100毫米的铜带;
在真空或惰性气体的烘箱中，将叶片和它的端梢加热到700℃～950℃，并将该温度保持30～70分钟;
将温度降到环境温度。
用这种方法，叶片、铜带和端梢之间的焊接是同时进行且为最佳。此外，至少部分地将钛碳化物变成熔融状态，使得端梢的硬度大于50HRC。
如果端梢的硬度要大于60HRC，则温度要提高，然后降温度，在温度为450℃～500℃时保持6小时，然后下降到环境温度。在此阶段，实际上将全部钛碳化物变成熔融状态，并同时进行了减小应力的热处理。
本发明的一个实施例将通过下列附图作为例子予以说明。
图1为本发明固定在叶片上的钛碳化物的端梢。
图2为图1所示叶片的平面图。
图3为图1所示叶片的剖面。
图1所示蒸汽透平叶片有根部1和带有进气边3和排气边4的扭曲叶身2。端梢覆盖了叶片2宽度的三分之一以上。铜带6置于叶片和端梢之间（见图2和图3）。
叶片用钛合金制成，端梢5的成份为：
Tic：28%～40%
Cr+Co：12%～26%
Mo：1%～6%
Ni：3%～8%
Cu：0.3%～1.5%
Fe：其他部分
具有较好效果的两种特殊成份是：
Tic Cr Co Mo Ni Cu Fe
成份1：32% 20% 0% 2% 3% 1% 其他部分
成份2：33% 14% 9% 5% 6% 0.8% 其他部分
端梢是通过机加工的粉末烧结和压实得到的，端梢的长度与欲保护的叶片部分长度相等（500毫米），它的宽度是足够的。它的形状是平直的或弯曲的，有或没有角度或弯成圆形，其目的是为了与叶片的进气边相配合。
叶片2和端梢5之间余层的机加工精度不大于1/10毫米。
准备好的叶片，通过插在叶片2和端梢5之间其厚度为7/100毫米～15/100毫米的铜带，将端梢5焊接在叶片2上。
为了进行焊接，叶片2和端梢5一起被放入烘箱，端梢5用2～3个钼压板加热。
温度升高到900℃～950℃之间，根据叶片进气边的厚度将该温度保持30～75分钟，然后烘箱被冷却到环境温度。
除了焊接外，通过将大部分的钛碳化物变成熔融状态使端梢与结构硬化处理，该端梢5的硬度为50HRC～55HRC。
为了进一步提高端梢5的硬度，要进行下述的附加处理：
将烘箱的温度升高到450℃～500℃并使它保持4～6小时，从而使全部钛碳化物基本上成熔融状态，同时完成减小应力的处理。
