Abstract The anti-oxidation behavior of boron aluminosilicate glass-ceramic materials with different MoO3 content deposited on titanium in temperatures range 850–1050 °C were investigated. The experimental results showed that in comparison with the bare titanium, the weight gain of specimen without MoO3 decreased from 18.7 to 0.6 mg/cm2 after 100 h oxidation at 850 °C.The addition of MoO3 was able to provide further decrease on the oxidation rate of titanium from 0.6 to 0.1 mg/cm2. The 20 wt.% MoO3 system measured the least weight gain and maximum tensile strength which was between the substrate and the coating for 30.1 MPa at 850 °C for 100 h whilst led to the peak retained strength value with 8.7 MPa after 30 times thermal cycles to 700 °C. The EDS line scanning images revealed that a molybdenum rich interlayer was detected in between the substrate and coating layer with average width of about 2 μm and it was believed that it did play an essential part in blocking the inward diffusion of oxygen to titanium.

MoO 3 对硼铝硅酸盐微晶玻璃涂层增强钛高温抗氧化性能的影响

摘要 研究了不同 MoO3 含量的硼铝硅酸盐微晶玻璃材料在 850-1050 °C 温度范围内沉积在钛上的抗氧化行为。实验结果表明，与裸钛相比，不含 MoO3 的试样在 850 °C 氧化 100 h 后的增重从 18.7 mg/cm2 降低到 0.6 mg/cm2。添加 MoO3 能够进一步降低氧化速率0.6 至 0.1 mg/cm2 的钛。20 wt.% MoO3 体系在 30.1 MPa、850 °C 和 100 小时的条件下测量了基材和涂层之间的最小增重和最大拉伸强度，同时在 30 次热循环后产生 8.7 MPa 的峰值保留强度到 700 °C。
