“…They have been widely used in aircraft and aerospace as thermal protection systems (TPS) [1][2][3][4]. However, the ablation resistance of C/SiC cannot meet the requirements of TPS in the environments with high-speed gas flow washout and high-pressure because the protecting silica layer becomes active at ultrahigh temperatures [5,6].…”

“…In oxyacetylene flame environment, the composite surface was heated to around 1300°C in a short period of time, facilitating a heterogeneous reaction between ceramic phases and oxygen species on the surface of the composites. The possible reactions during ablation testing are as follows:

SiC false(s false) + {normalO}_{2} false(g false) \to SiO false(g false) + CO false(g false)

2 SiO false(s false) + {normalO}_{2} false(g false) \to 2 {SiO}_{2} false(s false)

C false(s false) + {normalO}_{2} false(g false) \to {CO}_{2} false(g false)

2 C false(s false) + {normalO}_{2} false(g false) \to 2 CO false(g false)

CO false(g false) + {normalO}_{2} false(g false) \to 2 {CO}_{2} false(g false)

The slurry reactive melt infiltration (RMI) method was used to overcome the shortcomings of the traditional RMI method utilized in preparing the large‐irregular shaped C/C preform. C/C–SiC composite was successfully fabricated via PCS–Si slurry RMI. Results show that it has a favorable physical bonding between the PCS–Si slurry and the C/C preform. After RMI, most of the Si in the PCS–Si slurry coating infiltrated into the C/C preform, the density of the C/C preform increased from 1.24 to 1.52g cm−3, and the open porosity decreased from 27.22% to 18.04%. SiC was formed on the surface as well as in the pores of the C/C preform. The as‐received C/C–SiC composite showed a pseudo‐ductile fracture behavior with a flexural strength of 76.4MPa. The mass ablation rate of the C/C–SiC composite is 0.34 mg s−1, exhibiting much better ablation resistance than the C/C preform with a mass ablation rate of 1.80 mg s−1.

This paper concentrates on the measurement and analysis of laser ablation effect of particularly prepared aerospace material, polycarbosilane (PCS). Laser ablation experiment setup is designed and built, based on a continuous-wave high-power solid-state laser (CWHPSSL). Steel samples with composite PCS coating are prepared. After that, a group of laser ablation experiment is performed. The samples are shot by laser beam with thousands W/cm 2 fluence. The results, including the ablation morphology and temperature data, is shown and discussed. Temperature data gives a good demonstration of thermal protection effect of composite coating, and in the meanwhile the morphological features in the ablated region reveal the principle of PCS laser-proof effect. Theoretical investigation has also been carried out. The temperature field is simulated based on Fourier equation of heat conduction, and the simulation result provides a good demonstration on thermal-proof effect of PCS coating layer during laser ablation process.
