To support the application for piston of advanced internal combustion engine and pantograph slide plate of high-speed rail, cyclic ablation with different loading spectrums in alternate plasma combustion and compressed air flow were performed by adjusting single impacting time to understand the characteristics of C/C-SiC-ZrB₂-ZrC composites in high frequent pulsing fluid at ultra-high temperature. When the loading time increased from 0.5 to 5 s, the ablation rates rose sharply while the surface temperature changed incrementally. Ablation morphology indicated that the change of dominant ablation mechanism from mechanical erosion to chemical reaction resulted in the sharp rise of the ablation rates.

为支持先进内燃机活塞和高铁受电弓滑板的应用，通过调整单次冲击时间，在交替等离子燃烧和压缩空气流中进行不同载荷谱的循环烧蚀，了解C/C特性-SiC-ZrB ₂ -ZrC复合材料在超高温高频脉动流体中的研究。当加载时间从 0.5 秒增加到 5 秒时，烧蚀速率急剧上升，而表面温度逐渐变化。烧蚀形态表明，主要烧蚀机制从机械侵蚀转变为化学反应，导致烧蚀率急剧上升。
