摘要：
A novel Al-Si composite coating was fabricated on gamma-TiAl by the combination of magnetron sputtered Al coating and subsequently electrodeposited SiO2 coating. The oxidation performance of the specimens was evaluated in static air at 900 degrees C. Results shown that the Al Si composite coating can act as an efficient oxygen migration barrier and provide good oxidation resistance. During the oxidation process, an Al2O3 enriched layer formed beneath the composite coating. The interfacial reaction between the composite coating and alloy resulted in the generation of Al2O3 and Ti5Si3.
