Abstract

The effect of implantation of argon, oxygen, and nitrogen ions on the physicochemical structure of the surface and the corrosion and electrochemical behavior of chromium-nickel steel 03Cr18Ni11 has been studied. Methods of electrochemical polarization (EP), atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS) were used. Ion implantation of argon, oxygen, and nitrogen leads to an increase in the corrosion resistance of steel 03Cr18Ni11 both in a neutral environment and in the presence of a corrosion activator (chloride anions), while irradiation with argon ions is most effective. It is found that, after implantation of argon ions, a partial etching of the steel surface occurs, i.e., an increase in the true surface. This, in turn, facilitates the onset of the passive state. At the same time, the use of oxygen and nitrogen ions leads to smoothing of the surface. AFM data indicate that the studied steel treated with argon ions exhibits the greatest resistance to local corrosion. The implantation of oxygen and argon ions reduces the overall corrosion to the greatest extent. It is important to note that deep craters and traces of pitting corrosion do not form on the surface of the steel. The XPS data show that after ion implantation, there is a change in the concentration of the elements that make up the steel in the near-surface layers of the material in the depth of the implanted layer compared with the unirradiated sample. It is established that the surface layers of steel are enriched in chromium atoms during ion implantation. This process occurs most intensively when samples are treated with argon ions. In this case, mixed chromium and iron oxides are formed, contributing to the passivation of the steel surface. Also, the process of ion implantation is accompanied by oxidation of the surface of the steel under study. This is confirmed by an increase in the oxygen content in the surface layers. To the greatest extent, this process occurs during the implantation of oxygen ions. After corrosion tests, an increased chromium content is also observed on the surface of steel treated with Ar⁺ ions, which confirms the formation in this case of stable chromium oxides that remain on the surface during the corrosion of steel. The analysis of the fine structure of the XPS spectra showed that, under the action of argon ions, the oxygen of surface oxides is redistributed in favor of chromium atoms and the formation of stable mixed iron and chromium oxides of the spinel type, including Fe²⁺, Fe³⁺, Cr³⁺, and Cr⁶⁺ compounds. It is important to note that, although chromium oxides are also formed during oxygen implantation and in the same quantities as during argon implantation, the protective properties of the resulting compounds are noticeably lower. Therefore, not only the chemical composition but also the structure of the resulting layers are important. It can be assumed that the high kinetic energy of heavy argon ions affects both the formation of developed surface relief and the formation of stable mixed iron and chromium oxides of the spinel type.

铬镍钢 03Cr18Ni11 在氩、氧和氮离子注入过程中的成分和腐蚀电化学特性变化

摘要研究了氩离子、氧离子和氮离子植入对铬镍钢 03Cr18Ni11 表面物理化学结构以及腐蚀和电化学行为的影响。研究采用了电化学极化（EP）、原子力显微镜（AFM）和 X 射线光电子能谱（XPS）等方法。氩、氧和氮的离子注入可提高 03Cr18Ni11 钢在中性环境和存在腐蚀活化剂（氯阴离子）时的耐腐蚀性，而氩离子的辐照最为有效。研究发现，植入氩离子后，钢表面会发生部分蚀刻，即真实表面增加。这反过来又促进了被动状态的出现。同时，氧离子和氮离子的使用会使表面变得平滑。原子力显微镜数据表明，用氩离子处理过的钢材具有最强的抗局部腐蚀能力。氧离子和氩离子的植入能最大程度地减少整体腐蚀。值得注意的是，钢表面没有形成深坑和点蚀痕迹。XPS 数据显示，离子注入后，与未经辐照的样品相比，构成钢的元素在材料近表层的浓度在植入层深度发生了变化。已经证实，在离子注入过程中，钢的表层富含铬原子。在用氩离子处理样品时，这一过程最为剧烈。在这种情况下，会形成铬和铁的混合氧化物，有助于钢表面的钝化。此外，在离子注入过程中，所研究钢材的表面也会发生氧化。表层氧含量的增加证实了这一点。在最大程度上，这一过程发生在氧离子植入过程中。腐蚀试验后，在用 Ar+ 离子处理过的钢材表面还观察到铬含量增加，这证实了在这种情况下形成了稳定的铬氧化物，在钢材腐蚀过程中留在表面。对 XPS 光谱精细结构的分析表明，在氩离子的作用下，表面氧化物中的氧重新分布，有利于铬原子，并形成稳定的尖晶石型铁铬混合氧化物，包括 Fe2+、Fe3+、Cr3+ 和 Cr6+ 化合物。值得注意的是，虽然在氧气植入过程中也会形成铬氧化物，且数量与氩气植入过程相同，但所形成的化合物的保护性能明显较低。因此，不仅化学成分很重要，所得层的结构也很重要。可以认为，重氩离子的高动能既影响了表面浮雕的形成，也影响了稳定的尖晶石型铁铬混合氧化物的形成。

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
