Quasicrystals are a special type of structure that has amazing physical and chemical properties. They are composed of periodic but non-repeating unit cells, the symmetry of which is forbidden in three-dimensional space. Such irregular crystal structures are a sequence of atoms organized according to a specific algorithm that does not obey the usual laws of crystallography. The study of the thermochemical stability of quasicrystals plays an important role in understanding their behavior under various conditions.

To achieve this goal, the method of cold gas-dynamic spraying was used. This method is the process of applying a coating to the surface of a material by spraying and depositing it at high gas velocities. In this case, a mixture consisting of 30% Cu and 70% quasicrystals was used, which was deposited on the sample.

The results of the study showed that the quasicrystal obtained by cold gas-dynamic spraying has high thermochemical stability. The thermal stability of quasicrystals in this system means that they retain their structure and properties even at high temperatures. This is an important property for the potential applications of these materials in various industries such as energy, electronics and catalytic processes.

In summary, this study successfully investigated the thermochemical stability of quasicrystals in a highly filled QM system containing 30% Cu and 70% quasicrystals produced by cold gas dynamic sputtering. The studies carried out allow us to conclude that this material is highly stable at elevated temperatures. This represents an important advance in the understanding and application of quasicrystals in various fields of science and technology.
