Abstract The corrosion resistance of nanocrystallized IN738 coating fabricated by magnetron sputtering technique has been evaluated by elect rochemical methods and surface analysis technique such as SEM、STM.The dissoluti on rate of IN738 coating was higher than that of IN738 alloy and the pitting res istance was deteriorated for the defects engendered during sputtering process.Ho wever,the corrosion resistance of nanocrystallized IN738 coating was high enough for the application requirement.

Key words: magnetron sputtering IN738 coating corrosion resistanc
