Description
技术领域
本发明属于高温防护涂层及其制备技术领域，具体涉及一种适于抗高温铝渗透非浸润性涂层及其制备方法。
背景技术
铝合金材料在日常生活和国防军工领域都有巨大的应用，如铝合金窗、高温结构件和飞行器表面材料等方面。金属铝的提取和熔炼是制造高性能铝合金的第一步，目前主要通过电解铝的方式得到金属铝。电解铝就是通过电解得到的铝。现代电解铝工业生产采用冰晶石-氧化铝融盐电解法。熔融冰晶石是溶剂，氧化铝作为溶质，以碳素体作为阳极，铝液作为阴极，通入强大的直流电后，在950℃-970℃下，在电解槽内的两极上进行电化学反应，即电解。铝电解生产可分为侧插阳极棒自焙槽、上插阳极棒自焙槽和预焙阳极槽三大类。自焙槽生产电解铝技术有装备简单、建设周期短、投资少的特点，但却有烟气无法处理，污染环境严重，机械化困难，劳动强度大，不易大型化，单槽产量低等一些不易克服的缺点，当前已基本上被淘汰。当前世界上大部分国家及生产企业都在使用大型预焙槽，槽的电流强度很大，不仅自动化程度高，能耗低，单槽产量高，而且满足了环保法规的要求。电解铝过程中目前主要存在的问题是高温下熔融状态的铝溶液将会与电解炉壁及钢壳铝芯阳极爪的表面金属材料如不锈钢反应，导致炉膛和钢壳的失效，如何解决由于铝液发生渗透并与钢壳等发生反应导致其失效是当前的关键问题。
因此，针对上述存在的技术缺陷问题，急需设计和开发一种适于抗高温铝渗透非浸润性涂层及其制备方法。
发明内容
本发明的第一目的在于提供一种适于抗高温铝渗透非浸润性涂层，本发明的另一目的在于提供一种适于抗高温铝渗透非浸润性涂层的制备方法。
本发明的第一目的是这样实现的，所述涂层依次由合金基体、粘结层和表面陶瓷层组成；其中所述粘结层厚度范围为50-100微米；所述表面陶瓷层厚度范围为100-500微米；
本发明的另一目的是这样实现的，所述方法具体包括如下步骤：
通过大气等离子喷涂的方式在合金基体表面制备致密50-100微米厚的粘结层合金，即使制备的合金涂层具有一定的气孔率，由于层状结构特点孔隙之间相互不连接也使得粘结层具有优异的阻铝传播作用；
将粘结层防止在空气中一段时间后由于其富含铝将会在表面生成致密的氧化铝膜作为抗氧化层存在，从而进一步保护合金基体；
通过电子束物理气相沉积在粘结层表面制备厚度为100-500微米厚的具有柱状晶结构的致密抗铝渗透非浸润性表面陶瓷层。
本发明通过适于抗高温铝渗透非浸润性涂层，所述涂层依次由合金基体、粘结层和表面陶瓷层组成；其中所述粘结层厚度范围为50-100微米；所述表面陶瓷层厚度范围为100-500微米；以及所述涂层的制备方法，得到一种种抗高温铝渗透的非浸润性涂层材料，使得在电解铝过程中的槽壁和钢壳铝芯阳极爪等零部件避免与铝溶液接触反应，提高相关设备的服役寿命，节约生产成本和提高生产效率。

本发明还提供一种适于抗高温铝渗透非浸润性涂层的制备方法，所述方法具体包括如下步骤：
通过大气等离子喷涂的方式在合金基体表面制备致密50-100微米厚的粘结层合金，即使制备的合金涂层具有一定的气孔率，由于层状结构特点孔隙之间相互不连接也使得粘结层具有优异的阻铝传播作用；
将粘结层防止在空气中一段时间后由于其富含铝将会在表面生成致密的氧化铝膜作为抗氧化层存在，从而进一步保护合金基体；

所述方法中，还包括如下步骤：通过电子束物理气象沉积技术制备表面陶瓷层，柱状晶结构的涂层组织形貌具有疏铝溶液浸润性的特点，通过结构调控加强涂层的抗铝渗透性能。
所述方法中，还包括如下步骤：制备粘结层的工艺为大气等离子喷涂或者电子束物理气象沉积，并且在制备完成后将其放置在空气中一段时间在其表面形成纳米级的致密氧化铝保护膜。
也就是说，在本发明方案中，提供一种抗高温铝渗透非浸润性涂层及其制备技术，所述涂层体系由合金基体+粘结层+表面陶瓷层组成，其中粘结层厚度为50-100微米，表面陶瓷层厚度为100-500微米；
合金基体材料包括锆基、铜基、镁基、铁基、镍基、钴基、铝基和钛基等合金材料；
粘结层材料为MCrAlY、NiAl和NiCr-Al中的一种，其中MCrAlY为NiCrCoAlY、NiCoCrAlY、CoNiCrAlY或CoCrAlY；
表面陶瓷层材料为ATa1-yNbyO4或者A3Ta1-xNbxO7中的一种，其中A为Al和稀土元素中的一种或者多种，且x和y的值均为0-1之间；
具体地，制备粘结层的工艺为大气等离子喷涂或者电子束物理气象沉积，并且在制备完成后将其放置在空气中一段时间在其表面形成纳米级的致密氧化铝保护膜；
通过电子束物理气象沉积技术制备表面陶瓷层，柱状晶结构的涂层组织形貌具有疏铝溶液浸润性的特点，通过结构调控加强涂层的抗铝渗透性能；
涂层制备过程中主要涉及以下步骤：
通过大气等离子喷涂的方式在合金基体表面制备致密50-100微米厚的粘结层合金，即使制备的合金涂层具有一定的气孔率，由于层状结构特点孔隙之间相互不连接也使得粘结层具有优异的阻铝传播作用；
将粘结层防止在空气中一段时间后由于其富含铝将会在表面生成致密的氧化铝膜作为抗氧化层存在，从而进一步保护合金基体；
通过电子束物理气相沉积在粘结层表面制备厚度为100-500微米厚的具有柱状晶结构的致密抗铝渗透非浸润性表面陶瓷层。
换言之，本发明的目的是提供一种抗高温铝渗透非浸润性涂层及其制备技术，以解决目前电解铝过程中熔融状态的铝溶液与槽壁和钢壳铝芯阳极爪等零部件/位置接触产生渗透和腐蚀反应，导致其失效的问题。
为实现上述目标，本发明提供如下技术方案：一种抗高温铝渗透非浸润性涂层体系由合金基体+粘结层+表面陶瓷层组成，其中粘结层的作用是提高陶瓷层与基体的结合强度延长涂层服役寿命，同时粘结层在空气中即可生产一层致密的氧化膜进一步起到饱和合金基体的作用；表面陶瓷层为致密的柱状晶结构具有疏铝溶液的特点，使得熔融铝溶液在涂层表面具有优异的流动性从而减小涂层与铝溶液反应的可能性；再者，表面陶瓷层材料与铝具有优异的高温相容性，难以与铝溶液发生反应阻止铝溶液进入涂层内部与合金基体反应。
本技术方案的有益效果是：
本技术方案中依次在合金基体表面制备粘结层和表面陶瓷层，其中通过大气等离子喷涂的方法制备粘结层获得层状结构，即使粘结层中含有气孔也会相互隔离阻隔铝液的渗透和传播，同时在空气中放置一段时间后在粘结层表面会形成致密氧化膜进一步提供保护作用；通过电子束物理气相沉积在粘结层表面制备柱状晶的表面陶瓷层，所用陶瓷材料本身具有疏铝特性，与铝溶液接触角大于90°，而柱状的表面结构特点能够使涂层获得超疏铝特点，从而提供优异的抗铝渗透效应，获得一种非铝浸润性的涂层材料。
综上所述，本发明具有以下技术效果：粘结层材料为MCrAlY、NiAl和NiCr-Al中的一种，其中MCrAlY为NiCrCoAlY、NiCoCrAlY、CoNiCrAlY或CoCrAlY，上述合金均具有大量的铝元素从而提高了粘结层的抗铝渗透性能，同时在空气中或者高温环境中使用一段时间后在粘结层表面会形成致密的氧化铝膜进一步提高材料的抗铝渗透特性；粘结层的存在也能够有效提高合金基体与表面陶瓷层的结合强度从而延长涂层和相关零部件的服役寿命；
选择大气等离子喷涂的方式制备粘结层是为了获得层状结构的致密涂层材料，即使涂层中存在一定的孔隙和裂纹等利用层状结构可以将孔隙和裂纹相互隔离，从而防止铝溶液通过孔隙和裂纹直接渗透进入材料内部与合金基体反应；
表面陶瓷层材料为ATa1-yNbyO4或者A3Ta1-xNbxO7中的一种，其中A为Al和稀土元素中的一种或者多种，且x和y的值均为0-1之间；上述陶瓷材料与铝具有优异的高温化学相容性，即难以发生反应和渗透保证铝液不与合金基体接触反应；同时上述陶瓷材料具有极低的热导率，因此有效降低合金基体表面的温度，如电解铝温度为900-1000℃，制备涂层后将提供100-300℃的降温梯度，降低合金表面温度能够阻止/延缓其与铝溶液反应的发生；
表层陶瓷材料具有疏铝溶液的特点，铝溶液在陶瓷表面流动性优异能够顺利从其表面滑落从而阻止反应渗透的发生；同时通过电子束物理气相沉积的方式制备得到柱状晶结构的陶瓷层将进一步提高陶瓷的铝液非浸润性
整个材料体系由合金基体+粘结层+表面陶瓷层组成，且在粘结层表面存在致密氧化铝膜，存在合金基体/粘结层、粘结层/氧化膜和氧化膜/表面陶瓷层三种界面，界面热阻的存在结合低热导率陶瓷表面能够有效降低合金材料表面热导率。
也就是说，通过在钢壳等合金材料表面制备由粘结层和表面陶瓷层组成的材料体系，并通过陶瓷层的显微组织调控制备得到一种抗高温铝渗透的非浸润性涂层材料，使得在电解铝过程中的槽壁和钢壳铝芯阳极爪等零部件避免与铝溶液接触反应，提高相关设备的服役寿命，节约生产成本和提高生产效率。
实施例
通过大气等离子喷涂的方式在合金基体表面制备致密50-100微米厚的粘结层，大气等离子喷涂工艺参数如下：喷枪功率为35~40 kW，喷枪距离为120~200 mm，氩气和氢气的气体流量分别为5~8 slpm、6~12 slpm，进料速度为35~60 g/min，喷枪速度为100~300 mm/s，喷涂时间为1~3 min；将粘结层防止在空气中一段时间后由于其富含铝将会在表面生成致密的氧化铝膜作为抗氧化层存在，从而进一步保护合金基体；通过电子束物理气相沉积在粘结层表面制备厚度为100-500微米厚的具有柱状晶结构的致密抗铝渗透非浸润性的陶瓷层。电子束物理气象沉积时的参数为：抽真空处理真空度低于5×10-3 Pa，随后加热基体温度至200-300℃，靶基距离为200-300 mm，入射角度为25-30°，电子的加速电压为20-30kV，沉积速率为300-500 nm/min，经过一定时间后沉积得到100-500微米厚的柱状晶涂层。实施例1-8和对比例1-6的涂层成分、涂层厚度和制备参数分别如表1和表2所示。
表1粘结层和陶瓷层成分及厚度
表2涂层制备参数
说明：
对比例1与实施例1的区别在与粘结层厚度过厚，导致涂层使用过程中应力较大，易于脱落
对比例2与实施例1的区别在于陶瓷层过厚，涂层与基底结合强度低易于脱落；
对比例3与实施例1的区别在粘结层厚度过薄，粘结层不足以提供足够的结合强度；
对比例4与实施例1的区别在陶瓷层过薄，铝溶液渗透陶瓷层腐蚀内部金属基底；
对比例5与实施例1的区别在同时使用大气等离子喷涂工艺制备陶瓷层和粘结层，使得陶瓷层与铝溶液的接触角极小，与铝溶液具有相互浸润的作用，使得涂层被铝溶液渗透腐蚀基底；
对比例6与实施例1的区别在同时使用电子束物理气象沉积的方式制备粘结层和陶瓷层，使得粘结层提供的粘结力不足，陶瓷层易于剥落，同时整体为柱状晶的结构使得铝溶液能够沿晶界腐蚀渗透涂层和基底。
