| 英文摘要 | The hot corrosion resistance of a new directional solidification (DS) Ni-based super-alloy DZ68 was studied and compared with K438 alloy. The results indicate that the microstructure of DZ68 alloy is more uniform than K438 alloy after heat treatment. There are small size carbides in the microstructure of DZ68 alloy after heat treatment, but there are big size carbides and a lot (gamma + gamma') eutectic in the microstructure of K438 alloy. The hot corrosion of DZ68 alloy is uniform, and the corrosion products are mainly (Ni, Co)Cr(2)O(4) and Al(2)O(3), More (Ni, Co)Cr(2)O(4) exists in outer corrosion layer and more Al(2)O(3) exists in inner corrosion layer. For the K438 alloy the hot corrosion is not uniform, NiO is the mainly corrosion product in outer corrosion layer and CrS is the main corrosion product in inner corrosion layer, Moreover, the segregation of Ti can induce segregation of other elements in the two alloys, which leads to a severe local corrosion of alloys. Under the same experimental condition, the corrosion resistance of DZ68 alloy is a little better than that of K438 alloy. |
