摘要

In this study, the wall thickness-to-diameter ratio of hollow spheres was controlled using a repetitive coating method, and their compressive performance was evaluated. The results indicate that changes in the number of coating layers and template sizes significantly affect the formation of hollow spheres, with both wall thickness-to-diameter ratio and density showing a significant impact on compressive performance. Specifically, larger diameters increase the likelihood of cracking during sintering, leading to lower formation rates. The specific energy absorption performance increases with the wall thickness-to-diameter ratio, reaching a peak at a ratio of 0.063. Based on these key findings, a systematic preparation process is proposed for batch production of hollow spheres with consistent compressive performance, providing effective technical support for material performance control.
