Abstract
本发明包括基于镍的合金，并且所述基于镍的合金至少包含(以重量％计)：钴(Co)27.0％至29.0％、铬(Cr)16.0％至18.0％、铝(Al)11.6％至12.6％、钇(Y)0.3％至0.5％、铁(Fe)4.0％至5.0％，任选的钽(Ta)0.6％至0.8％、钼(Mo)0.4％至0.6％、硅(Si)0.4％至0.6％，剩余部分的镍(Ni)。
Description
本发明涉及特别地用于燃气轮机的基于NiCoCrAl的合金的组合物、粉末、涂层和组件。
当在当前的燃气轮机开发中进一步提高发动机效率、输出功率、可用性和可靠性时，通常受到用于防止热腐蚀和氧化的保护涂层的温度容量和寿命的限制，并且受到在热的涡轮机组件上结合热屏障涂层(TBC)的限制。
当前所使用的涂层几乎不能满足进一步的涡轮机开发的需求。另一方面，它们还由于大量的昂贵元素铼(Re)而过于昂贵。纵观世界范围内基于NiCoCrAl的涂层的最新发展，全部都聚焦于在涂层中添加大量的稀土元素或贵金属例如Gd、La、Pt等以实现更高的温度容量和更长的寿命。
这种趋势与市场中元素的大幅价格增涨相冲突。
在当今可获得的基于NiCoCrAlY的涂层中，人们非常依赖于钇(Y)并入以具有钉扎(pegging)和清除作用，从而提高涂层的抗氧化性和耐腐蚀性。
然而，最近有报道称，MCrAlY顶层上的保护性氧化铝氧化皮中的氧化钇夹杂物提供了快速的氧扩散路径，因此加速了涂层的氧化(Nijdam TJ,Sloof WG.Acta Materialia2007；55:5980)。
当前MCrAlY中存在的>10ppm的高硫含量缩短了涂层寿命(Smialek JL,Jayne DT,Schaeffer JC,Murphy WH.Thin Solid Films 1994；253:285；以及SmialekJL.Metallurgical Transactions A,Physical Metallurgy and Materials Science1991；22A:739)。
该问题还没有得到解决。
因此，本发明的目的是克服上述问题。
通过权利要求1的合金，通过权利要求5的粉末，通过权利要求6的涂层并且通过根据权利要求7的层系统解决该问题。
本发明的另外的优点列于可以彼此任意组合以产生另外的优点的从属权利要求中。
本发明通过利用最新的研究结果和升级的热力学模型来设计优化和创新的基于NiCoCrAlX的合金涂层来解决该问题，所述合金涂层通过在空气、真空或保护气氛中热喷涂，物理沉积，以及在基于镍(Ni)或钴(Co)的超级合金上镀覆来施加，其中X代表次元素例如Y、Si、Hf、Ta、Fe、Mo等的组合。
在当前基于NiCoCrAlY的涂层中代替钇(Y)或部分替代钇(Y)，引入其他次元素来部分地替代钇(Y)的功能以保持低的钇(Y)含量。该构思也是为了避免或最小化昂贵元素的使用，以仍然满足当今先进的燃气轮机的增长的需求。
铁(Fe)的引入允许使显微组织或涂层中的富铝(Al)相稳定，并在一定程度上降低铝(Al)的消耗速率。
此外，设计和制造创新的基于NiCoCrAlX的涂层的另一种方法是将硫(S)含量降低至≤10ppm，以进一步增加涂层寿命。
根据应用的类型和施加方法，涂层厚度应在30μm至800μm的范围内。
新的基于NiCoCrAlX的涂层是基于Ni的，并具有以下组成(以重量％计)：27％至29％的Co、16％至18％的Cr、11.6％至12.6％的Al、0.3％至0.5％的Y、4.0％至5.0％的Fe、0.6％至0.8％的Ta，以及任选的0.4％至0.6％的Mo、0.4％至0.6％的Si。
因此，本发明包括NiCoCrAlYFeTa、NiCoCrAlYFeTaMo、NiCoCrAlYFeTaSi、NiCoCrAlYFeTaMoSi。
本发明得到了具有比当今可获得的NiCoCrAlY涂层更高的温度容量、更长的寿命和更低的成本的基于NiCoCrAlX的涂层。
如果用作磨料涂层，则可以将具有这种合金组成的粉末与粘结剂和/或耐火金属或陶瓷混合。
对于涡轮机应用，特别地，使用其上施加有本发明的涂层的金属基底例如基于镍或钴的超级合金。
该涂层特别地通过热喷涂法例如APS、VPS或HVOF来施加。
甚至SLM、SLS或任何AM技术都可以施加这种合金的涂层或生产这种合金的块体组件。
层系统至少包括
金属基底，
特别是基于镍的超级合金，和
至少具有本发明的合金的涂层，以及任选的在金属结合和氧化涂层顶部上的陶瓷层。
陶瓷层优选地包含部分或完全稳定的基于氧化锆的组合物。
