| 摘要: |
| 采用耐温的磷酸盐玻璃和改性的β–SiC吸收剂的热喷涂材料体系，使用火焰喷涂工艺制备了热喷涂雷达吸波涂层，对粉末、涂层制备过程及性能进行了研究，结果表明：喷雾干燥造粒是制备热喷涂雷达吸波涂层粉末材料体系的合理方法，使用火焰喷涂制备的涂层，吸收剂含量为20 %时，涂层性能最佳，当涂层厚度为1 mm时，在1.2×1010～1.8×1010 Hz范围内，涂层反射率均低于?8 dB。 |

| Abstract: |
| Fabricated the thermal spray radar absorbing coatings by flame spray, which used the thermal spray material system with modified β–SiC and phosphate glass. Analyzed the powder and coatings fabrication process and performance, the results indicated: spray dried is the appropriate way to fabricate the powder of thermal spray radar absorbing coatings. When the coating thickness is 1 mm and the content of absorbent is 20 %, the flame spray absorbing coatings have the best performance, and the reflectivity of the coating is less than ?8dB between the radar waveband of 1.2×1010 to 1.8×1010 Hz. |
