| 摘 要： | 采用微弧离子表面改性技术在TC11合金表面制备阻燃涂层,采用扫描电镜、透射电镜、XRD等方法分析了阻燃涂层组织及物相,采用“钛火”液滴法试验平台测试了TC11钛合金在300～700 ℃之间的燃烧参数,验证了同等试验条件下带有阻燃涂层TC11钛合金试样在300～700 ℃之间的阻燃有效性. 结果表明,制备的阻燃涂层主要由TiZr非晶相组成,涂层致密,与基体为冶金结合,700 ℃以内具有一定的阻燃性能,分析阻燃涂层的阻燃机理主要为涂层吸收能量,减小基体对热量的吸收,同时阻止钛合金与氧接触机制来阻燃.

| Abstract: | Burn-resistant coatings were deposited on TC11 titanium alloys by Micro-arc ion surface modification technology. The SEM, TEM and the X-ray diffraction technologies were employed to analyze microstructure and phases of the coating. The combustion parameters of TC11 titanium alloys and the fire-resistant performance of the coatings were measured by titanium fire melt liquid-drop method experimental rig. The results showed that the coating contained TiZr amorphous phases and displayed rather dense, while the serviceability temperature under 700 ℃ the coating had fire-resistant performance. The burn-resistant coatings absorbed energy,and reduced energy which absorbed by substrate. In the same time,these coatings prevent titanium alloy from meeting oxygen. |
