摘　　要：抗氧化性差是影响钛合金在航空航天领域广泛应用的重要因素,提高抗氧化性成为钛合金研究的一个主要方向。玻璃-陶瓷涂层具有较宽的软化温度范围、良好的化学稳定性、高的机械强度,可作为钛合金高温抗氧化涂层。总结了钛合金表面抗氧化涂层材料的性能要求及玻璃-陶瓷抗氧化涂层材料的优缺点,综述了国内外钛合金表面抗氧化玻璃-陶瓷涂层的研究进展;展望了钛合金表面抗氧化玻璃-陶瓷涂层的发展方向。Titanium alloys suffer from the serious disadvantages of poor high temperature oxidation resistance, which prevent them from being applied in the aircraft industry. Improving their oxidation resistance is becoming one major direction of titanium alloy research. Glass-ceramic coatings have a wide range of softening temperature, excellent chemical stability, superior mechanical properties, which can be used as high temperature oxidation-resistant coatings on titanium alloys. In the paper, the performance requirements of high temperature oxidation-resistant coatings on the titanium alloy and the advantages and disadvantagesof oxidation-resistant glass-ceramic coatings are summarized. Research progress of oxidation-resistant glass- ceramics are reviewed. The development trend of oxidation-resistant glass-ceramic coatings on the titanium alloy is predicted.
