Abstract

通过使用含锰的、具有锆、钽和碳的钴基合金实现良好的材料配合的接合连接。

Description

基于钴的、含锰的高温焊料合金、粉末、构件和焊接方法
技术领域
本发明涉及一种能够在焊接时使用的含锰的钴基合金、一种粉末、一种构件和一种焊接方法。
背景技术
由于其与镍基合金相比的高的导热性，第一涡轮级的固定的组件部分地由钴基合金、如MAR-M 509制造。这适合用于固定式燃气轮机和航空涡轮机。
主要提供镍基焊料用于在这些组件处的材料配合的接合连接，所述组件构成为高温焊接部的形式。这些传统的镍基焊料包含硼和/或硅作为熔点抑制剂(Schmelzpunkterniedriger)。由于钴和镍的不同的热膨胀系数，在接合区的范围中出现高的固有应力，所述固有应力导致接合连接的削弱。此外，在宽的接缝和短的焊接工艺时间的情况下，脆性相沉淀在焊缝中，所述脆性相附加地损害机械的完整性。
迄今，使用传统的镍基焊料来接合钴基材料。在此，接受在接合区的范围中机械特性的显著受限。
发明内容
因此，本发明的目的是阐明一种焊料合金、一种粉末、一种构件和一种焊接方法，其中钴基合金能够在高温下被焊接并且形成良好的接合连接。
所述目的通过根据本发明的实施例所述的焊料合金、根据本发明的实施例所述的粉末、根据本发明的实施例所述的构件和根据本发明的实施例所述的方法来实现。
在下述说明书中列出其他有利的措施，这些措施能够彼此任意组合，以便获得其他优点。
通过新型钴合金取消使用传统的镍焊料。此外，新型焊料优选不需要典型的熔点抑制剂硼和硅，所述熔点抑制剂会导致形成脆性的第二相。
在＜1473K的温度范围中含锰的钴焊料的可加工性能够实现将接合工艺集成到钴组分的热处理中。由此产生时间和成本节约。
具体实施方式
说明书仅描述本发明的实施例。
提出以新型的不含硼和硅的钴基焊料进行工作，所述钴基焊料包含锰(Mn)作为主要的熔点抑制剂。也优选的是，不存在其他熔点抑制剂镓(Ga)和锗(Ge)。
基于钴的焊料合金至少具有：
锆(Zr)，尤其8重量％至16重量％、更尤其15重量％的锆(Zr)，
钽(Ta)，尤其6重量％至10重量％、更尤其8重量％的钽(Ta)，
碳(C)，尤其0.5重量％至1.5重量％、更尤其1重量％的碳(C)，
锰(Mn)，尤其8重量％至12重量％、更尤其10重量％的锰(Mn)，可选的钛(Ti)。
优选将四元体系Co-15Zr-8Ta-1C(以重量％表示)考虑作为输出体系，所述四元体系与锰制成合金。
锰(Mn)在钴基体之内具有高的溶解度，使得能够防止脆性相的沉淀。
熔点能够通过添加10重量％的锰(Mn)而下降到＜1473K。
此外，能够混合0.5重量％至5重量％的少量的钛(Ti)，以进一步降低熔点。此外，除钽(Ta)之外，钛在钴基体中起到碳化物形成元素的作用并且因此用于加固接合区。
用基于钴的焊料合金焊接的衬底的明显不同之处在于：所述衬底尤其具有其他元素或者尤其不具有锰。
