摘要: 本文叙述了用料浆喷雾干燥法制取复合粉末材料工艺的研究,包括实验用小型喷雾干燥装置及流程设计、料浆制备、喷雾干燥工艺等。测定了所获得复合粉末的性能,进行了等离子喷涂试验,检查了涂层的性能。认为,用料桨干燥法可以制备出喷涂需要的不同功能的复合粉末,因而具有广阔的发展前景和应用领域。

Abstract: A study of technology for producing composite powders by spray-drying of slurry, including the design of experimental equipment and process, preperation of slurry and spray-drying technology, etc. is described in detail in this paper. The properties of the composite powders obtained were determined and the plasma spraying experiments were carried out to examine the properties of coating layers. The slurry spray-drying method is considered to be of good prospects and wide applications in producing various composite powders being suitable for coating.
