中文摘要: |
随着等离子喷涂技术的发展,等离子喷涂氧化铝基复合涂层在防腐蚀、耐磨损和航天航空等领域得到了广泛应用。首先简要介绍了新型等离子喷涂技术(激光等离子喷涂、悬浮液等离子喷涂和超音速等离子等)和主要喷涂工艺参数(喷涂功率、送粉方式和喷涂距离等),然后从改善涂层耐腐蚀性能的角度出发,阐述了第二相、喷涂工艺参数和后处理工艺对涂层气孔率的影响及与涂层耐腐蚀性能的关系。重点分析了硬度、喂料特征和激光熔覆技术对氧化铝基复合涂层耐磨损性能的影响,详述了影响硬度的因素,以及喷涂粉末特征和激光熔覆处理对复合涂层微观结构的影响。在电磁波吸收性能研究方面,论述了吸收剂含量、涂层厚度和多种电磁波吸收剂匹配以及喷涂参数的调整对等离子喷涂氧化铝基复合涂层吸波性能的影响。最后对以等离子喷涂技术制备性能更加优异的氧化铝基复合涂层提出了展望。 |

With the development of plasma spraying technology, plasma-sprayed Al2O3-based composite coatings have been widely used in the fields of corrosion protection, wear resistance, aerospace, etc. Firstly, new plasma spraying technologies (laser plasma spraying, suspension plasma spraying and supersonic plasma spraying) and main spraying parameters (spraying power, powder feeding method, spraying distance, etc.) were briefly introduced. Then, from the perspective of improving corrosion resistance of the coatings, effects of the second phase, spraying parameters and post-treatment process on porosity of the coatings as well as the relationship between the three factors and corrosion resistance of the coatings were expounded. Then the effects of hardness, feeding characteristics and laser cladding technology on wear resistance of Al2O3-based composite coatings were analyzed emphatically. Factors affecting the hardness, as well as effects of characteristics of spraying powder and laser cladding treatment on microstructure of the composite coating were described in detail. In the aspect of study on electromagnetic absorption properties, effects of adjusting absorber content, coating thickness, various electromagnetic wave absorber matching and spraying parameters on wave absorbing properties of plasma-sprayed Al2O3-based composite coatings were discussed. Finally, prospect of preparing Al2O3-based composite coatings exhibiting better performance by adopting plasma spraying technology were proposed. |
