Abstract
A novel silicon-aluminizing diffusion coating was prepared on γ-TiAl alloy by cold sprayed Al-12Si alloy coating and subsequent heat treatment. The oxidation resistance of silicon-aluminizing diffusion coating was studied at 900 °C for 1000 h and 120 cycles. The results showed that the coating decreased the inward oxygen diffusion and thus improved the oxidation resistance of bare alloy effectively. The microstructure evolution of the diffusion...
