| 首先，从热喷涂的后处理技术方向入手，重点综述了激光重熔后处理技术、热处理后处理技术的研究进展，简要分析了两种后处理技术对金属陶瓷涂层界面综合性能、界面结合强度、内聚强度、耐磨性、残余应力等的影响，指出外部因素(激光重熔参数、热处理工艺参数、材料种类、重熔方式和热处理的时间等)和内部因素(金属陶瓷涂层本身的特性)对两种后处理技术的影响。然后，介绍了几种材料后处理技术(喷丸和热等静压后处理技术)，分析了其对材料性能的影响。其次从微观层次入手，探索和分析了热喷涂后处理技术的原理和其中存在的问题，且对其研究和发展方向做出了预测。最后，在前人研究的基础上，结合近些年常用的涂层后处理技术和一些材料后处理技术，提出了采用一种新的后处理技术——感应重熔技术和超声深滚技术耦合对喷涂涂层实施后处理，且初步制定了研究的技术方案，并对其特色点和创新之处进行了总结，同时对该研究进行了可行性分析。 |
| 英文摘要: |
| Thermal spraying technology is an important surface technology in surface engineering and has been included in the national long-term plan to develop advanced manufacturing technology. Thermal spraying is a surface modification technology, and the interface between coating and substrate is the key to this technology. The paper first, from the perspective of post-processing technology of thermal spraying, reviewed the research progress of laser remelting post-processing technology and the heat treatment processing technology, brief analyzed the influence of the two kinds of post-processing techniques of ceramic coatings on metals comprehensive performance, the interface bonding strength, cohesive strength, wear resistance, residual stress, etc, and stated the influence of the external factors (laser remelting parameters, the heat treatment process parameters, the type of material, remelting method and heat treatment time, etc.) and the internal factor (the characteristics of the metal-ceramic coating itself) on the two kinds of post-processing technology. Then several materials post-treatment technologies (shot peening and hot isostatic pressing post-treatment) are introduced to analyze their effects on material properties. Secondly, from the perspective of micro-level, the principle and problems of thermal spray post-treatment technology are explored and analyzed, and the research and development direction is predicted. Finally, on the basis of previous studies, combined with coating processing technology and some material post-processing technology commonly used in recent years. This paper proposed a new post processing technology—coupling of induction remelting technology and ultrasonic deep rolling in post-treatment of sprayed coating, made a preliminary technical plan, summarized its features and innovations, and conducted an feasibility analysis. |
