| 摘要 |
The present invention provides a method for producing a multilayer structure, comprising the steps of: providing a composition comprising a Fe—Cr alloy powder and at least one of the oxides of Fe, Cr, Ni, Co, Zn, Cu; forming a first layer of said composition; forming at least one additional layer on one side of said first layer; heat treating said layers in an oxygen-containing atmosphere; and sintering in a reducing atmosphere so as to provide a final alloy, wherein the amount of Fe in the final alloy of the first layer after the sintering step is in the range of from about 50-90% by weight, based on the total weight of the final alloy. |
