Description

一种燃气轮机透平叶片热障涂层及其制备方法
技术领域
本发明属于燃气轮机透平叶片防护涂层技术领域，特别提供一种燃气轮机透平叶片低成本、长寿命、高可靠性热障涂层及其制备方法。
背景技术
燃气轮机透平叶片服役环境恶劣，长期经受高温燃气的冲击和侵蚀，其表面需涂敷由抗氧化腐蚀性能良好的MCrAlY金属粘结底层，其中M为Ni、Co或Ni+Co，和导热系数低的Y2O3部分稳定的ZrO2，即YSZ陶瓷面层组成的热障涂层TBCs，以提高其抗烧蚀能力，延长其服役寿命和可靠性。
MCrAlY粘结层作为陶瓷面层和高温合金基体之间的过渡层，其作用主要有两个：一是降低陶瓷面层和高温合金基体之间由于热膨胀系数不匹配所引起的热应力；二是提高整个热障涂层体系的抗氧化腐蚀性能。为了满足燃气轮机叶片对长寿命、高可靠性热障涂层的需求，MCrAlY粘结层既要结构致密又要有较大粗糙度。
为了满足这个需求，商用MCrAlY底层一般采用低压等离子LPPS或真空等离子VPS喷涂方法制备。这两种方法制备的涂层致密，且粗糙度良好，但生产成本高。为了降低生产成本，人们提出了采用超音速火焰喷涂HVOF法制备MCrAlY底层或大气等离子喷涂APS法制备MCrAlY底层代替LPPS/VPS制备MCrAlY底层的方案。
但这两种方法均存在缺点：HVOF法制备MCrAlY底层表面粗糙度低、与等离子喷涂YSZ面层结合力差；APS法制备MCrAlY底层孔隙率高，抗氧化性能不好，难以满足燃气轮机叶片对长寿命、高可靠性热障涂层的需求。
因此如何保证MCrAlY底层结构致密又要具有较大粗糙度，成为发展燃气轮机叶片低成本、长寿命、高可靠性热障涂层的关键问题。
发明内容
本发明的目的在于提供一种燃气轮机透平叶片高可靠性热障涂层及其制备方法，该涂层体系具有抗氧化腐蚀性能良好、界面结合强度高等优点，解决了燃气轮机透平叶片对低成本、长寿命热障涂层的需求。
本发明技术方案如下：
一种燃气轮机透平叶片热障涂层，其特征在于，所述热障涂层由内到外分别为MCrAlY(M＝Ni,Co或Ni+Co)致密层、MCrAlY(M＝Ni,Co或Ni+Co)粗糙层和YSZ(Y2O3部分稳定的ZrO2)陶瓷面层。
其中，所述MCrAlY粗糙层表面粗糙度Ra大于8μm。
MCrAlY致密层厚度为0.07-0.15mm；MCrAlY粗糙层厚度为0.05-0.07mm；YSZ陶瓷面层厚度为0.20-0.50mm。
本发明所述燃气轮机透平叶片热障涂层的制备方法为：
1)、采用超音速喷涂粒径为-88+16μm的MCrAlY粉末在零件表面制备0.07-0.15mm的MCrAlY致密层；
2)、采用超音速喷涂粒径为-90+38μm的MCrAlY粉末在零件表面制备0.05-0.07mm的MCrAlY粗糙层；
3)、对喷涂完上述涂层零件进行真空热处理；
4)、采用大气等离子喷涂方法在零件表面制备0.20-0.50mm的YSZ陶瓷面层。
其中，步骤3)中热处理制度为：加热到1050℃±10℃，保温3h±0.5h，叶片随炉冷却至200℃以下，充氩气0.08-0.10MPa，冷却至80℃以下出炉；加热保温过程中，真空室内压强应不大于0.665MPa。
本发明的有益效果为：
本发明采用超音速喷涂方法制备MCrAlY底层，解决了LPPS/VPS法制备MCrAlY底层方案成本昂贵的问题；采用超音速喷涂方法制备致密层和粗糙层解决了HVOF法制备MCrAlY底层表面粗糙度低、APS法制备MCrAlY底层孔隙率高的问题，同时使得MCrAlY底层结构致密，提高底层与基体的结合力，中间粗糙层具有较大粗糙度，提高了其与YSZ陶瓷面层的结合强度；本发明所述热处理步骤进一步提高了整个涂层体系的综合性能，提高了其服役寿命和可靠性，进一步降低生产成本。

图1为在高温合金基体上热障涂层喷涂态截面形貌，其中，A区为YSZ面层，B区为HVOF法制备的MCrAlY粗糙层，C区为HVOF法制备的MCrAlY致密层，D区为高温合金基体。
具体实施方式
实施例1
以燃气轮机一级透平叶片高温合金基体材料为载体制备热障涂层，工艺流程为：来件检查→丙酮除油污→外观检查→干吹砂→清理→夹具保护→装夹→预热→超音速喷涂MCrAlY致密层→超音速喷涂MCrAlY粗糙层→热处理→等离子喷涂YSZ面层→检验。
喷涂前干吹砂处理是为了清洁和活化零件合金表面，从而提高MCrAlY底层与合金基体之间的结合强度。
涂层制备步骤为：
1)、超音速喷涂MCrAlY(M＝Ni)致密层，厚度为0.13mm，喷涂所用MCrAlY粉末粒径为-88+16μm；
2)、超音速喷涂MCrAlY(M＝Ni)粗糙层，厚度为0.07mm，喷涂所用MCrAlY粉末粒径为-90+38μm；粗糙层喷涂完后表面粗糙度Ra为10μm；
3)、对喷涂完的涂层零件进行真空热处理，热处理制度为：在1050℃下保温3h，叶片随炉冷却至200℃以下，充氩气0.10MPa，冷却至80℃以下出炉，加热保温过程中，真空室内压强应不大于0.665MPa；
4)、等离子喷涂YSZ面层，厚度为0.20mm。
图1为在高温合金基体上热障涂层喷涂态截面形貌，从图可以观察到，靠近基体侧MCrAlY涂层结构致密，表面平整，靠近YSZ陶瓷侧MCrAlY涂层表面粗糙，有利于APS YSZ面层和MCrAlY涂层结面的结合。

超音速喷涂MCrAlY(M＝Ni+Co)致密层厚度为0.09mm；超音速喷涂MCrAlY(M＝Ni+Co)粗糙层厚度为0.05mm；粗糙层喷涂完后表面粗糙度Ra为12μm；等离子喷涂YSZ面层厚度为0.35mm。该热障涂层具有抗氧化腐蚀性能良好、界面结合强度高等优点。

与实施例1的不同之处在于：
超音速喷涂MCrAlY(M＝Co)致密层厚度为0.15mm；超音速喷涂MCrAlY(M＝Co)粗糙层厚度为0.06mm；粗糙层喷涂完后表面粗糙度Ra大于10μm；等离子喷涂YSZ面层厚度为0.45mm。该热障涂层具有抗氧化腐蚀性能良好、界面结合强度高等优点。
本发明未尽事宜为公知技术。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
