Description

一种镍基钎焊合金组合物
技术领域
本发明涉及一种镍基钎焊合金组合物。
背景技术
为了有效地在高温环境下发挥作用，通常加入重合金组分以强化高温合金。这可导致极端环境下使用的高温合金部件(如燃气轮机中的热气通道的螺旋浆)焊接连接/修补的困难。由于其降低的成本与周期，钎焊成为高温合金部件连接/修补的更优的选择。然而，使钎焊接头/修补具有接近高温合金基材材料的某些性能，特别是延展性可能是有挑战性的。通常，首要障碍可能是在钎焊接头中形成了脆性相。硼已经广泛应用于钎焊合金，但通常脆性硼化物导致钎焊接头的低劣的机械性能。提高钎焊接头/修补区域的机械完整性的方法通常需要采用延长的扩散周期。通过与基材高温合金或钎焊粉末混合物均化，这种方法可以降低脆性硼化物相的量。但是这种方法可能需要延长的周期时间，更高的成本并令基材高温合金遭受热劣化。
发明内容
为了解决上述技术问题，本发明提供了一种镍基钎焊合金组合物，所述合金组合物包含如下重量份数的各组分:9-25wt％的铬；5-45wt％的钼；和0.05-6wt％的硼，剩余为至少一种选自铝、钛、钨、钴、铁、锆、铌、铼、碳。
有益效果
该钎焊合金能够连接/修补具有复杂形状的高温合金制品，并可以在高温应用中使用。
具体实施方式
本发明提供了一种镍基钎焊合金组合物，所述合金组合物包含如下重量份数的各组分:9-25wt％的铬；5-45wt％的钼；和0.05-6wt％的硼，剩余为至少一种选自铝、钛、钨、钴、铁、锆、铌、铼、碳。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应所述以权利要求的保护范围为准。
