Abstract The sputtered nanocrystalline coating of K38G alloy was obtained by means of magnetron sputtering.The corrosion behavior of cast K3 8G alloy and its sputtered nanocrystalline coating with a solid NaCl deposit in dry air or in wet oxygen at 600℃~700℃ was studied.The results indicated that the mass gain of the coating was higher than that of the cast alloy.Nanocrystall ization reduced corrosion resistance of the K38G alloy.The relevant corrosion me chanisms were discussed.
