Abstract

In order to study the mechanism of C/C-SiC composites, the C/C-SiC composite specimens are placed in the jet containing particles, and the erosion rate of the specimens under different working conditions is measured; the surface and internal micro morphology of the specimens after erosion are observed by scanning electron microscopy (SEM) and micro CT, and the erosion mechanism is analyzed. The results show that the linear erosion rate is 2.24 times of the ablative rate, and the mass erosion rate is 1.8 times of the ablative rate. The particle erosion plays a decisive role in the consumption of the specimen; the brittle failure of the composite occurs under the mechanical erosion.

Key words： particle erosion; C/C-SiC composite material; erosion rate; mechanism
