IPC: C23C8/12
Filed: 1991-10-16
Abstract: PURPOSE:To improve the oxidation resistance of a casting in a high temp. atmosphere by fanning an aluminum impregnated layer on the surface layer part of a malleable iron casting. CONSTITUTION:The stock of malleable iron subjected to decarburizing annealing is buried in an aluminum impregnant in a case for aluminum impregnating treatment. This case is closed and is held at about 1000 deg.C for about 1Ohr in a reducing atmosphere to impregnate aluminum into the surface layer part. As the aluminum impregnant, e. g., the one obtd. by adding about 1 to 5% ammonium chloride to the powder of an Al-Fe allay (50:50) is used. By this treatment, as for the aluminum content in the aluminum impregnated layer formed on the surface layer part, it is about 30$ on the surface part, and, to the inside, it reaches the depth of about 0.6 to 1mm while it reduces one- dimensionally. By this treatment, the use of the malleable iron casting in the high temp. air is made possible.
