In this study, the architecture of a multilayer metallic material of iron-carbon alloys with an internal protector was developed based on theoretical studies. The operability of the proposed architecture was experimentally verified using gravimetry and electrochemical analysis. The internal position of the protector enabled the modification of the mechanism of corrosion. The stages of corrosion of the multilayer material were revealed; the material was observed as useable until the third layer was perforated. To demonstrate the obtained results, the authors conducted a set of experiments using X-ray microscopy and scanning electron microscopy with an electron probe analysis of the chemical composition. The cost of the developed material is within the same range as widely used corrosion-resistant stainless austenite steels; and in terms of corrosion resistance, this material is comparable to palladium, molybdenum, nickel, and Hastelloy.
在本研究中，基于理论研究开发了一种带有内部保护剂的铁碳合金多层金属材料结构。通过重量法和电化学分析对所提出结构的可操作性进行了实验验证。保护剂的内部位置能够改变腐蚀机制。揭示了多层材料的腐蚀阶段；观察到该材料在第三层穿孔之前仍可使用。为了展示所得结果，作者使用X射线显微镜和扫描电子显微镜并结合化学成分的电子探针分析进行了一系列实验。所开发材料的成本与广泛使用的耐腐蚀不锈钢奥氏体钢处于同一范围内；在耐腐蚀性方面，这种材料可与钯、钼、镍和哈氏合金相媲美。
