Description

一种热障涂层材料
技术领域
本发明属于高温热障涂层技术及相关涂层材料。
背景技术
随着航空、航天及火力发电等民用技术的发展，涡流发动机热端部件的使用温度要求愈来愈高，高温合金及其单晶的使用已达到了材料的极限状态。在这种情况下，从材料的角度考虑，另一种降低发动机叶片工作温度的可行技术----热障涂层技术得到了广泛的应用。
美国宇航局的对比研究表明，ZrO2的综合性能较为优越。在1000℃时，ZrO2的热膨胀系数为11×10-6K-1，最接近基体合金的热膨胀系数，而导热系数仅为2.1-2.2Wm-1K-1。但纯ZrO2在通常使用温度范围内，会发生四方相(t)向单斜相(m)的马氏体相变，为了使涂层适应高温下的热循环工作环境并提高涂层的寿命，通常在ZrO2中添加少量稳定剂来控制、减少这类相变的发生。美国专利5,789,330(Kondo，et al)中报道了在ZrO2中掺杂0.1wt％-40wt％各种相稳定剂如Y2O3、CaO、MgO、Sc2O3，稀土氧化物等后得到的热障涂层材料。材料烧结后体系中单斜相占25-75％，涂层材料的长期使用最高温度低于1200℃。美国专利6,231,991中报道了一种具有烧绿石结构的材料，特别是La2Zr2O7作为热障涂层材料，它有独特的性质如较低的热导率、在熔化之前也没有相变。但La2Zr2O7热膨胀系数较YSZ小，同基体合金的热膨胀系数相差更大，因高温热膨胀不匹配所导致的涂层内应力将更加严重，涂层循环寿命短。
发明内容
本发明的目的是提供一种热障涂层材料；
本发明的另一个目的是提供一种热障涂层材料的制备方法；
本发明的第三个目的是提供一种热障涂层材料的应用。
本发明利用陶瓷的高耐热性、抗腐蚀性和低导热性，实现对基体的保护。因此，热障涂层陶瓷表面层材料的选择需要遵循一定的原则：高熔点、在室温和使用温度之间无相变、低热传导率、化学反应惰性、较高的热膨胀系数、良好的抗热冲击性能、较低的烧结速度。
CeO2为一种萤石结构氧化物，其热传导系数随温度升高呈指数衰减，比8YSZ小，而热膨胀系数较8YSZ大，接近镍基高温合金的热膨胀系数。CeO2作为热障涂层材料可以提高涂层的耐热冲击性能，这是因为：1)涂层不发生四方晶系到单斜晶系的转变；2)涂层具有良好的隔热性能，可以降低金属基底的温度从而降低金属基底的氧化程度；3)涂层热膨胀系数大。但纯CeO2由于高的氧扩散速率以及高温下快速的烧结速率而不适合单独使用。本发明中，我们通过在CeO2体系中掺杂稀土锆酸盐0.5R2O3-nZrO2，0.9≥n≥0，R为Nd、Sm、Eu、Gd和Tb中一种或两种以上的组合，获得了高热膨胀系数、低热传导速率和低烧结速率的高温热障涂层材料。
本发明陶瓷材料具有下述化学组成(1-n)CeO2-nZrO2-0.5R2O3，0.9≥n≥0，R为Nd、Sm、Eu、Gd或Tb中一种或两种以上的组合。
制备步骤如下：
将CeO2、ZrO2、R2O3三种粉末按(1-n)∶n∶0.5，0.9≥n≥0摩尔比混合，R为Nd、Sm、Eu、Gd或Tb中一种或两种以上的组合，球磨1-72小时，在1200℃-1600℃加热2-24小时，依照上述条件需重复球磨加热一至三次。
热障涂层材料的应用如下：首先，获得金属基底，金属基底为由镍基或钴基高温合金组成的部件；然后在金属基底表面或某一部位沉积一层金属粘结层，金属粘结层为MCrAlY合金，其中M为Ni、Co和Fe中一种或其组合，Y为Y、La或Hf中一种，金属粘结层厚度100至200μm；最后，在粘结层表面沉积陶瓷面层，陶瓷面层厚度200至600μm，陶瓷面层化学组成为(1-n)CeO2-nZrO2-0.5R2O3，0.9≥n≥0，R为Nd、Sm、Eu、Gd或Tb中一种或两种以上的组合。
本发明中热障涂层材料具有高热膨胀系数，室温至1200℃热膨胀系数在12×10-6K-1以上，优于目前普遍应用的热障涂层材料，在1400℃长期煅烧或淬火至室温，该材料仍保持稳定的晶体结构。此材料设计成为热障涂层材料，适于温度高于1150℃的高温环境应用。本发明中热障涂层材料可以通过如下途径沉积：等离子喷涂、电子束物理气相沉积。
附图说明
图1给出了热障涂层材料CeO2-0.5Nd2O3在室温至1250℃下的热膨胀系数变化，同时给出粘结层合金和标准8YSZ粉末热膨胀系数。图中显示该陶瓷材料具有高的热膨胀系数，室温至1250℃热膨胀系数为12.8×10-6K-1，优于目前普遍应用的热障涂层材料。而且其热膨胀趋势同粘结层合金的热膨胀趋势非常吻合，有利于消除热循环过程中金属与陶瓷涂层之间的热应力，可以显著提高涂层的抗热震性能，延长涂层的使用寿命。
图2给出制备所得热障涂层粉末样品CeO2-0.5Nd2O3的XRD谱图，采用CuK。辐射，管流20mA，管压40kV。图中显示粉末样品CeO2-0.5Nd2O3具有萤石结构。
本发明所得热障材料热膨胀系数较大，同发动机热端部件基体高温合金最为接近，从而以此材料沉积所得涂层内部热应力很小，热循环寿命长；市场易得；涂层制备方法简单，设备易得。
