Abstract

878,183. Preventing corrosion. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 27, 1958 [July 3, 1957], No. 20970/57. Class 123(1) Damage by flaking which occurs in the course of time to the coating of nitride formed on the interior surface of a steel vessel to protect it from corrosion by molten bizmuth at 550‹C. contained therein, the nitride layer having been formed by the combination with the nitrogen in the steel of zirconium or titanium added to the bismuth, is continuously repaired by replenishing the nitride coating and renewing it on the damaged areas, the nitrogen ions required for the formation of the new layer migrating through the walls of the vessel from a nitride coating formed on the outer surface thereof. To form the outer coating the vessel is jacketted and dry ammonia is supplied continuously to the jacket.
