摘要：
The present study deals with the oxidation behaviour of three Co-17Re-18Cr-XNi (X = 8, 15, 25 at.%) alloys and one Co-17Re-18Cr-15Ni-2Si alloy in the temperature range 800 degrees C-1100 degrees C. The experimental results reveal improved oxidation resistance with increasing Ni concentration. It seems that Ni enhances the diffusion of Cr. However, higher Ni concentrations accelerate the formation of the Cr-rich sigma phase detracting significant amounts of Cr from the matrix and deteriorating the corrosion resistance. Results of the oxidation tests reveal a positive effect of Si on the oxidation behaviour at 900 degrees C-1100 degrees C. It was found that Si enhances the Cr activity, though, facilitating the formation of the sigma phase.
