【摘要】：大气等离子体喷涂技术是一种常用的涂层制备工艺。作为所制备涂层的结构基元,单片层的形貌特征及堆叠行为决定了涂层的微结构,对涂层性能产生显著影响。本文较为系统地综述了与熔滴自身理化状态相关的主体因素、与沉积涂层的衬底相关的客体因素以及环境因素等对单片层形成过程的影响,着重分析了粉体尺寸、衬底预热过程等产生的多种不同影响及其之间的关联性,并通过对所述文献涉及实验方法各自特点的比较,提出未来的实验和模拟研究或都将向着与真实生产条件更加接近的方向发展。
[Abstract]:Atmospheric plasma spraying is a common coating preparation technology. As the structural elements of the coatings, the morphology and stacking behavior of the monolithic coatings determine the microstructure of the coatings, and have a significant effect on the properties of the coatings. In this paper, the effects of host factors related to the physical and chemical state of the droplet, the guest factors related to the substrate of the deposited coating and the environmental factors on the formation process of the monolayer are systematically reviewed, with emphasis on the size of the powder. A variety of different effects, such as the substrate preheating process, and their correlations, and a comparison of the characteristics of the experimental methods involved in the literature, It is suggested that future experimental and simulation studies may be closer to real production conditions.
