摘要

A SiO_2-Al_2O_3-glass composite coating was prepared on Ti-6A1-4V alloy by air spraying and subsequent firing. The oxidation behavior of the specimens at 800 ℃ and 900 ℃ for 100 h was studied. The thermal shock resistance of the coating was tested by heating up to 900 ℃ and then quenching in water. The composite coating acted as an oxygen migration barrier and exhibited good resistance against high temperature oxidation, thermal shock, and oxygen permeation on the Ti-6A1-4V alloy. Coating/alloy interfacial reaction occurred, forming a Ti_5Si_3/Ti_3AI bilayer structure. A thin AI_2O_3 rich layer formed beneath the composite coating during oxidation at 900 ℃.
