Abstract—Metal additive manufacturing is widely studied for its unique advantages over traditional manufacturing processes. It is used to form complex components of Ti, Fe, or Ni alloys. However, for nonferrous alloys—aluminum, magnesium, copper—additive technologies are not used because of rapid melting during laser, electron beam, and/or arc treatment. Cold spraying is widely used as an effective technology for applying high quality coatings in the mass production of metal and alloy products and/or metal matrix composite coatings. In addition, cold spraying is a serious and effective tool for the additive manufacturing of metals, and research in this area is currently becoming intense. It is shown in the work that the use of cold spraying technology makes it possible to obtain composite materials based on aluminum and titanium reinforced with boron carbide. Zirconium dioxide chosen as the reinforcing component could not be introduced into the composite based on aluminum and nickel, which is most likely due to the large particle size. During thermal treatment of materials obtained by cold spraying, new chemical compounds are formed—both intermetallic compounds and hardening ceramic inclusions that increase the microhardness. At the same time, the microhardness increases by about 7 times, but the linear dimensions decrease, which is not observed in the system based on nickel aluminide. However, as a result of a change in the structure during chemical transformations, a change in the geometry of the product and the formation of pores can be observed.

冷气动态喷涂增材技术在铝化镍和铝化钛材料生产中的应用

金属增材制造因其相对于传统制造工艺的独特优势而受到广泛研究。它被用来形成钛、铁或镍合金的复杂成分。然而，对于有色合金——铝、镁、铜——添加剂技术不被使用，因为在激光、电子束和/或电弧处理过程中会迅速熔化。冷喷涂作为一种有效的技术被广泛应用于高质量的金属和合金产品和/或金属基复合涂层的批量生产。此外，冷喷涂是金属增材制造的一种重要而有效的工具，目前这一领域的研究正变得越来越激烈。研究表明，利用冷喷涂技术可以获得碳化硼增强铝钛基复合材料。在铝镍基复合材料中无法引入氧化锆作为增强成分，这很可能是由于铝镍基复合材料的粒径较大。在对冷喷涂材料进行热处理的过程中，会形成新的化合物——金属间化合物和硬化的陶瓷夹杂物，从而提高显微硬度。同时，显微硬度提高了约7倍，但线性尺寸减小，这在镍铝化物体系中没有观察到。然而，由于化学转化过程中结构的变化，可以观察到产物几何形状的变化和孔隙的形成。

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.
