Atmospheric plasma spraying (APS) is a well-established method to fabricate coatings. Since the coatings are piled up with splat, the morphology of splats is of significant importance for the microstructure and performance of coatings deposited by APS. In the current review, the influences of parameters in spraying processes on formation of splats were divided into three categories, namely the droplet-related factors, substrate-related factors and environmental-related factors. The influence of above mentioned factors on morphology of splats were systematically introduced. Among them, effect of powder size and substrates preheating were emphatically discussed. Future research direction was also pointed out based on the reviewed literature in this paper.

Key words: atmospheric plasma spraying, thermal barrier coatings, droplet, splat, review
