LAMINATED MOLDING, METHOD FOR PRODUCING THE SAME AND POWDER FOR LAMINATED MOLDING
To provide a laminated molding in which a highly adhesive oxide layer is formed on a body made of an iron base material.SOLUTION: Disclosed is a laminated molding in which an oxide layer is formed on a body made of an iron base material. The oxide layer is composed of a composite material in which at least FeO is dispersed in a matrix composed of Fe2SiO4. The composite material may comprise a specific compound having a coefficient of linear expansion greater than that of Fe2SiO4 and an electrical resistivity greater than that of FeO. Examples of such specific compounds include Cr2FeO4. The composite material includes, for example, Fe: 20-45% and Si: 2-12%, assuming that the whole material is 100 at%. The more FeO is composed of non-dendritic particles and finely dispersed in the matrix, the greater the electric resistance of the oxide layer tends to be. Such an oxide layer can function as an electrically insulating layer and a corrosion-resistant layer.SELECTED DRAWING: Figure 2
【課題】鉄基材からなる本体上に高密着性の酸化物層を形成した積層造形物を提供する。【解決手段】本発明は、鉄基材からなる本体上に酸化物層が形成された積層造形物である。酸化物層は、Ｆｅ２ＳｉＯ４からなるマトリックス中に、少なくともＦｅＯが分散した複合材からなる。複合材は、Ｆｅ２ＳｉＯ４よりも線膨張係数が大きく、ＦｅＯよりも電気抵抗率が大きい特定化合物を含んでもよい。このような特定化合物として、例えば、Ｃｒ２ＦｅＯ４がある。複合材は、例えば、その全体を１００ａｔ％として、Ｆｅ：２０～４５％、Ｓｉ：２～１２％含む。ＦｅＯが非樹枝状粒子からなり、マトリックス中に微細に分散しているほど、酸化物層の電気抵抗値は大きくなり易い。このような酸化物層は、電気絶縁層や耐食層として機能し得る。【選択図】図２
