摘要： A ferritic alloy with a wear resistive oxide scale is obtained through the steps of pressing a ferritic alloy powder containing aluminum into a powder compact of a desired configuration, sintering the powder compact in a non-oxidizing atmosphere to provide a resulting sintered product, and heat-treating the sintered product in an oxidizing gas atmosphere in order to precipitate in the surface thereof alumina in the form of an alumina scale as the wear resistive oxide scale which is responsible for improved surface hardness or wear resistance. Due to the inherent porous nature of the sintered product, the oxidizing gas can readily penetrate deep into the surface of sintered product to facilitate the oxidization of the product surface into the alumina scale, in addition to that the oxidization depth can be controlled such as by the density of the product, which makes it possible to readily control the thickness of the alumina scale. The resulting alumina scale has an improved scale adherence due to the ferritic structure of the alloy.

摘要： Fe-Cr-Ni-Al ferritic alloy capable of forming hot oxidation/corrosion resistive aluminum oxide scale in the surface thereof by exposure to oxidation environments at elevated temperatures. Due to the ferritic structure, the aluminum oxide scale is formed uniformly and densely to improve scale adherence, or prevent scale flaking. The mechanical properties of the ferritic alloy is considerably improved by incorporation of controlled amounts of Cr, Ni, and Al relative to each other, which are added to precipitate minute Ni-Al intermetallic compounds in the alloy matrix while retaining the ferritic structure. Such minute Ni-Al intermetallic compounds are thought to be responsible for improved mechanical properties, including high temperature strength, tensile strength, hardness and the like. Whereby, the alloy combine excellent hot oxidation/corrosion resistance and improved mechanical properties.
