Abstract
PURPOSE: To prevent oxidation of a metallic alloy member by placing a graphite plate, a graphite-contg. ceramic plate, etc. in contact with or in the vicinity of the member when the member is heated in the air.
CONSTITUTION: A metallic alloy member is heated in the air for soln. heat treatment, hardening, hot rolling, etc. At this time, a graphite plate, a graphite-contg. ceramic plate or carbon fiber felt is placed in contact with or in the vicinity of the member. Graphite reacts with oxygen in the air at high temp., forming a CO-based reducing atmosphere. Because of the presence of the reducing atmosphere, the member is hardly oxidized.
