摘要

The ablation resistant coating was prepared by using organic silicon resin, polyethylene carbon silane as binder and Al2O3, BN, SiC, ZrO2, SiO2, CF as filler. The physical and mechanical properties of the coating were characterized. The results show that the glass powder and BN play a key role to reduce cracks in the coating, as well as ZrO2 is crucial to improve the heat and ablation resistant capabilities of the coating. The 1mm 30CrMnSiA steel substrate with 600 μm coating would not be perforated by the ablation for 4 seconds from 3000°C oxygen acetylene flame. When radiated from laser with power density of 531 W/cm2 for 4s, the temperature of substrate can decrease more than 1000°C with the protection of 900 μm coating.
