The oxalation resistance ofthe ~Crystalline layer was much better than that of the CaSt LDZ125 alloy. The Oalde scalesformed on the cast LDZ125 alloy was composed of AJZO3 with small ~s of Cr, Ti and Nieddes. ~ 500 h Obeation, the colltelit of A12O3 in the chide scales reduce because of its spallation during exposure, and the oalde scale was mainly composed of CrZO3 and TiO2. The chidescale formed on the inicrocrystalline LDZ125 consists of Only o--AJsos which had excellent ad-hesion and did hot spall in the durstion of exposure. The beneficial ears of ndcrocrystallizstionon the O~ion resistance of the superalloy were discussed.
