The article presents a detailed comparative analysis of materials used in the Cold Spray technology, which is an innovative method of coating without the use of high temperatures. The study covers a wide range of materials, including metals (aluminum, titanium, copper, steel), their alloys, as well as modern composite materials with ceramic additives. The main objective of the work is to evaluate how the physical and chemical properties of these materials affect the spraying process and the final characteristics of the coatings, such as adhesion to the substrate, mechanical strength, resistance to corrosion, wear and thermal loads. The article considers key parameters that determine the effectiveness of the technology, in particular the size and shape of the particles, their plasticity, hardness, as well as the speed and temperature of the gas flow during application.

Based on the analysis of literary sources and the results of experimental studies, the authors compare the behavior of different materials in the Cold Spray process. For example, aluminum exhibits high ductility and ease of application, making it ideal for lightweight structures in the aviation industry, while titanium is distinguished by exceptional corrosion resistance, but requires optimization of spraying conditions due to its hardness. Copper, in turn, provides excellent electrical conductivity, which is relevant for electrical applications, and ceramic composites open up prospects for creating wear-resistant coatings in harsh operating conditions.

A separate section is devoted to assessing the technological limitations and advantages of each material. For example, the problem of particle oxidation during spraying is considered, as well as the influence of coating porosity on its functional properties. The results of the study are supported by experimental data obtained using modern analysis methods, such as scanning electron microscopy and mechanical testing.

In the conclusions, the authors provide practical recommendations for the selection of materials for gas-dynamic spraying depending on specific industrial tasks. In particular, the potential of the technology for aircraft construction (repair of turbine blades), energy (protection of surfaces from erosion) and the automotive industry (application of decorative and protective coatings) is emphasized. The article also touches on the prospects for the development of Cold Spray, including a combination with additive technologies for the creation of complex metal structures.
