摘要	The glass-alumina composite coatings were successfully prepared on the K38G superalloy substrates. Their isothermal oxidation and thermal shock behavior at 1000 degrees C were characterized. With a post-annealing process at 850 degrees C, the composite coatings possessed an improved protective effect for the alloy substrates from isothermal oxidation and a higher resistance to thermal shock. Crystallization from the glass matrix and interfacial reaction between the matrix and alumina inclusions, which caused the composites more refractory and tough, accounted for this improvement. The micromechanisms for the formation of oxidation results of spinel ZnCr2O4 were also discussed.
