Description

一种等离子热喷涂制备氮化物增强高熵合金涂层的方法
技术领域
本发明属于高能束表面处理领域，特别涉及采用等离子束合金化制备耐磨复合涂层的方法。
背景技术
铝合金因其密度小、强度高、加工性能好等性能得到广泛应用，成为应用最为广泛的有色合金，铝合金发展应用方面的研究也越来越多。但其硬度低、耐磨性差等缺点限制了其使用范围，采用热喷涂技术制备高硬度表面涂层是提高铝合金耐磨性的主要手段之一。高熵合金为由五个以上的元素组元按照等原子比或接近于等原子比合金化的合金，具有一些传统合金所无法比拟的优异机械性能，如高耐磨耐腐蚀性、高强度、高硬度、高韧性等，从而使其成为制作涂层的选择之一。高熵合金常含有一定的Al元素，因此对涂层成分不是特别敏感。等离子喷涂常采用Ar、N2或再添加部分H2气，以保护喷涂过程中避免熔融合金粉末氧化，在喷涂过程中因高温的电离作用使N气电离为活性的N原子，有利于与合金成分反应形成氮化物，本申请中通过添加一定的Cr、Al，不仅有利于形成高熵合金，而且能够利用喷涂过程中的Cr、Al与N发生氮化反应，形成细小的氮化物，有利于进一步提高涂层的硬度和耐磨性。
发明内容
高熵合金自身具有高强度和良好韧性，而且通过喷涂过程中氮气以电离作用可以使N活化，从而借助喷涂过程进一步反应形成弥散、细小的氮化物，能够制备氮化物增强高熵合金涂层，以提高铝制工件的耐磨性，并且在涂层工件结合处少量Al的熔化，不仅有利于提高结合强度，而且也不至于影响涂层高熵合金的优良性能。
本发明解决其技术问题所采用的制作方法包括下述工艺步骤：
步骤一、按一定比例经熔炼后雾化制备AlCoCrFeNiBSi合金粉末，其中Al的质量含量为16~18%，Cr的质量含量为20~22%，Fe的质量含量为20~22%，Co的质量含量为20~22%，B的质量含量为3~4%，Si的质量含量为3~4%，其余为Ni元素；喷涂合金粉末经高温熔炼后采用惰性气雾化制备。粒度在10-40μm；
步骤二、选取待强化的铝合金工件表面，对工件表面清除油污，然后喷砂毛化处理，达到表面粗糙度均匀，无反光；最后采用外热方式对工件表面进行预热，预热温度控制在250~300℃；
步骤三、采用热喷涂的方式对工件表面预喷涂Ni-Al粘结层，粘结层厚度控制在30-100μm，所用Ni-Al合金粉末的粒度为80-240μm，其成分中含Al质量为8~20%，其余为Ni。
步骤四、采用等离子喷涂设备对工件表面进行热喷涂，冷却后即为耐磨涂层。其喷涂工艺：喷涂枪距工件距离为90-120mm，工作电流为500-700A，工作电压为50-70V，N2气速度为30-50 升/min，H2速度为5-10 升/min，送粉量为38±42g/min，冷却气压为0.3-0.5MPa，喷涂枪移动速度为30-80mm/s。
本发明的有益效果是：
（1）本发明的工艺方法采用高熵合金作为耐磨涂层的基体，能够充分利用其特有的扩散速度慢、对成分变化不敏感的特性，使涂层具有更高的韧性、强度和耐磨性。
（2）采用的N2一方面可以作为保护气，另一方面又利用其电离分解使N具有活性，在喷涂过程中与活性元素Cr、Al反应形成高硬度弥散的CrN、AlN，从而进一步提高涂层的耐磨性。
