904#陶瓷—玻璃涂层对高温下钛合金的保护作用

Protect Effect of 904 Ceramic-Glass Coating on Titanium Alloy at HighTemperature

摘要:

研究了在高温条件下(1200℃保温5 h),904~#陶瓷-玻璃涂层对TA7、TC4、TC11合金的保护作用。通过俄歇质谱分析、X光相分析以及金相和显微硬度分析,比较了涂层样和空白样(未涂层)的表层在氧含量、氧化污染层厚度、显微组织和显微硬度等方面的差异,从而证实904~#陶瓷-玻璃涂层具有显著的保护能力。

Abstract:

The 904~# ceramic-glass coating is studied to protect titanium alloy at high temperature. The samples coated and uncoated were compared for oxygen content, oxygen polluted layer thickness, microstructure and micro-hardness by using Auger electron, X-ray, metallograph, as well as micro-hardness analyse. It is proved that the 904~# coating has a good protecting ability.
