Description
说明书。
技术领域
本文公开的主题的实施方案主要涉及基于硅化物的复合材料及其生产方法。
背景技术
对于燃气涡轮应用(叶片,喷嘴,护罩),使用镍基超合金。
然而,在这个领域中,镍基超合金遇到了一个基本限制,即它们的熔点。由于先进超合金在约1350℃的温度下熔化,只有在低于1150℃的温度下才能获得明显增强。
在这方面,对适用于燃气涡轮应用的新材料的调查正在开始加速,目的是超越超合金的机械和物理极限。只有通过提供结构材料的基本性能(例如热疲劳、抗氧化性、强度/重量比和断裂韧性)的改进才能达到预期的发展。存在两种不同类型的材料,其可以作为候选物来抵抗约1200℃的操作条件;第一种是结构陶瓷,例如SiC、Si3N4,而第二种是结构硅化物,例如MoSi2。
这样看来,开发包含MoSi2 + Si3N4体系的材料,其具有低密度、优异的抗氧化性、抗弯曲性和蠕变性。然而,迄今为止,通常由烧结产生的所述材料由于其低断裂韧性(低于10MPa m0.5)而不用于燃气涡轮应用。
概述
因此,一般需要适合于燃气涡轮应用的材料,其在操作条件下的热疲劳、低密度、抗氧化性、抗弯曲性、蠕变性和断裂韧性方面显示出良好的性质。
一个重要的想法是提供一种材料,其中在氧化物颗粒的存在下进行硅化物和Si3N4粉末共混以控制最终的微观结构和增强机械性质。
另一个重要的想法是改进所述材料的生产过程,从而克服对烧结过程观察到的限制。
本文公开的主题的第一实施方案对应于包含Mo、B、W、Nb、Ta、Ti、Cr、Co、Y或其组合的硅化物,Si3N4和至少一种选自氧化钇、氧化铈及其组合的氧化物的基于硅化物的复合材料。
本文公开的主题的第二实施方案对应于用于生产基于硅化物的复合材料的方法,所述方法包括以下步骤:
i)提供硅化物、Si3N4和至少一种氧化物的粉末,
ii)均匀共混所述粉末,
iii)将至少第一层共混粉末置于支撑表面上,
iv)通过启用功率源熔化所述粉末的至少一部分,所述源具有150-1000W的能量功率,和
v)使所述熔化的粉末冷却并凝固,从而获得所述基于硅化物的复合材料。
通常,可以进行所述方法直到获得基于硅化物的复合材料的所需厚度和形状。
本文公开的主题的第三实施方案对应于可通过上述方法获得的基于硅化物的复合材料。
通常,所述材料相对于常规超合金显示出显著改进的机械、物理和热性质。
本文公开的主题的第四实施方案对应于由上述材料制成的燃气涡轮热气路径(HGP)部件,例如叶片、喷嘴和护罩。
附图简述
并入本文并构成说明书的一部分的附图示出本发明的示例性实施方案,且与详细描述一起解释了这些实施方案。在附图中:

所得材料的微观结构是分散良好的硅化物和Si3N4粒子,所述粒子被颗粒边界相包围。在硅化物和Si3N4之间不发生反应且没有检测到裂纹,尽管两种化合物之间的热膨胀失配。将氧化物定位于认为是完全非晶的颗粒边界。

总而言之,最终的微观结构由Si3N4颗粒(α晶型的基本上为圆形,且β晶型的为针状),由硅化物颗粒和由在含有氧化物(氧化钇和氧化铈)的颗粒边界处的非晶相构成。
本文公开的主题的第二实施方案对应于用于生产基于硅化物的复合材料的方法,所述方法包括以下步骤:

在步骤iv)中,所述功率源可以是激光或电子束。优选地,所述功率源是激光。
具体地,步骤iv)可以通过直接金属激光熔化(DMLM)、选择性激光熔化(SLM)、选择性激光烧结(SLS)、激光金属成形(LMF)或电子束熔化(EBM)进行。
在优选的实施方案中,步骤iv)通过直接金属激光熔化(DMLM),更优选在约300W的能量功率下进行。
上述方法可以进行直到获得基于硅化物的复合材料的所需厚度和形状。在这方面,所述方法可以进一步包括以下步骤:
vi)将第二层共混粉末置于步骤v)中获得的基于硅化物的复合材料上,所述第二层至少部分覆盖所述材料表面,
vii)重复步骤iv)和v),由此获得粘附到步骤v)的基于硅化物的复合材料的第二层基于硅化物的复合材料,和任选地
viii)通过放置第三和另外的层的共混粉末重复步骤vi)和vii),直到获得基于硅化物的复合材料的所需厚度和形状。
应注意,上述方法可以认为是增材制造方法,其中“增材”据说是至少一种氧化物。这种方法是便宜的、灵活的和有效的,由此复杂形状的机器部件可以容易地低成本生产。增材制造方法的使用对于涡轮机或燃气涡轮部件的生产将会是非常合乎需要的,涡轮机或燃气涡轮部件必须满足严格的要求,只要关系到在重操作条件下的机械阻力,例如在疲劳条件下的高温抗蠕变性。
上述方法允许从粉末开始逐层制造具有复杂形状的制品,粉末通过使用功率源局部熔化。如所述,优选的功率源是激光,如图1的示例性DMLM装置。在受控气氛下(例如使用惰性气体)和/或在真空条件下增材制造防止化学改变。
参考图1和2,可以如下示出通过使用DMLM装置进行的优选方法。
将来自粉末容器的第一层共混粉末(粉末3,图1)通过沿着放置在目标表面的一定高度的可移动台移动粉末材料容器一次或多次分布在可移动台(构建平台4,图1)上,例如借助于刮刀(刮刀6,图1)。粉末层厚度优选小于0.06mm(60微米),更优选小于0.04mm(40微米)。特别优选的是约0.02mm的层厚度。
一旦制备了第一层共混粉末(3,沉积(刮刀),图2),启用和控制功率源(激光1和激光束2,图1),以便在该层的期望部分(对应于待制造的最终产品的横截面)中局部熔化粉末(熔化部分5,图1)。功率源的能量功率优选为150-370W,更优选为约300W。
优选地布置功率源扫描间隔以提供相邻扫描线的实质重叠。通过功率源的重叠扫描使得能够通过随后的相邻扫描提供应力减小,且可以有效地提供连续热处理的材料。功率源扫描间距优选小于0.1mm(100微米),更优选小于0.05mm(50微米)。特别优选的是约0.03mm的扫描间隔。
在熔化后(4,熔化(激光),图2),使所得材料冷却并凝固。在待制造的最终产品的横截面的边界外的粉末(1,3D模型和2,切片(slicing),图2)保持粉末形式。
一旦如上所述加工第一层,则降低可移动台(5,降低平台,图2),且随后的共混粉末层分布在第一层的顶部上。共混粉末的第二层继而选择性熔化,随后使其冷却并凝固。进行熔化和凝固,使得每个层部分将粘附到之前形成的层部分。通过随后逐层加入一个共混粉末层,且选择性熔化并凝固对应于所需最终产品的随后的横截面的层部分,逐步重复所述方法,直到形成完整的最终产品,如图2示意性显示( 1,3D模型,和2,切片)。
一旦产品已经完成,未熔化和凝固的粉末可以去除并有利地再循环。
应了解,优选经由DMLM的熔化步骤允许获得粉末的熔合而不是烧结。通过这种方式,可以具有更均匀的微观结构,并避免颗粒之间烧结不足,从而导致机械脆性。此外,获得用于燃气涡轮应用的与AM技术相关的所有益处:避免昂贵的模具,降低成本,缩短交期,新设计。例如,这些基于硅化物的复合材料在燃气涡轮热气路径(HGP)部件上的应用将允许通过减少或避免部件冷却来提高燃气涡轮的功率和效率。由于上述材料,这通过设计不冷却部件(无内部冷却通道)是可能的,这促进部件金属温度提高。

c)将至少第一层共混粉末置于支撑表面上,
d)将粘合剂液滴沉积在所述共混粉末层上,
e)通过使用加热源使所述粉末干燥,从而获得所述基于硅化物的复合材料。
具体地,步骤c)至e)通过Binder Jet(BJ)进行。
在优选的实施方案中,所述粘合剂液滴是丙烯酸共聚物分散体树脂、聚碳硅烷、硅酮或其混合物的液滴。
上述方法可以进行直到获得基于硅化物的复合材料的所需厚度和形状。在这方面,所述方法可以进一步包括以下步骤:
f)将第二层共混粉末放置在步骤e)中获得的基于硅化物的复合材料上,所述第二层至少部分覆盖所述材料表面,
g)重复步骤c)和d),由此获得粘附到步骤e)的基于硅化物的复合材料的第二层基于硅化物的复合材料,和任选地
h)通过放置第三和另外的共混粉末层重复步骤f)和g),直到获得基于硅化物的复合材料的所需厚度和形状。

j)在惰性气氛中或在真空下在优选500-750℃的高温下脱脂,

在优选的实施方案中,所述材料具有在23℃下高于700MPa和在900℃下高于550MPa的极限拉伸强度(UTS)。

在更优选的实施方案中,所述材料包含α-Si3N4和β-Si3N4,后者是针状的。实际上,添加过程促进了针状β-Si3N4的生长;至少一种氧化物,优选为平均尺寸<50μm的晶粒形式,引起裂纹偏转,所以为了增加断裂韧性,这种类型的微观结构是合乎需要的。
所得材料的微观结构是分散良好的硅化物和由晶界相包围的Si3N4颗粒。在硅化物和Si3N4之间不发生反应且没有检测到裂纹,尽管在两种化合物之间的热膨胀失配。将氧化物定位于本应完全非晶的晶界。
