A methodology has been developed to ensure airworthiness by improving the reliability of structural elements of aviation and airfield equipment, which differs from the currently available ones by using new effective non-deformational technologies based on pulsating subsonic gas flows during all types of maintenance and repair. New technologies have been developed to improve the mechanical and operational properties of aircraft structural elements, applicable in the production of aviation equip-ment, in the process of its maintenance and repair, characterized by the ability to increase them in a complex, without deterioration of any parameters. The nature of the impact of unsteady subsonic gas flows on the structure and properties of aircraft structural elements made of metal and polymer materials, the stress states of products, and the corresponding physical model has been created. It is proposed to implement measures for the use of new non-deformational technologies for restoring operational properties, as well as improving the reliability and extending the life cycle of elements, parts and assemblies of aircraft, airfield equipment by transport companies that exceed the currently used efficiency, efficiency and envi-ronmental friendliness, making appropriate changes to the maintenance and repair regulations. The direction of improving the methodology for forecasting the technical condition of aircraft structural elements is indicated, which differs from the existing ones by taking into account data on the density of crystal structure defects in surface layers.

“…Due to differences in the values of heat input and properties of electrode materials, surfacing processes have a specific effect on the properties of coatings [5][6][7][8][9][10][11][12][13][14][15]. In paper [5], a study of the effect of adding copper to a metal under an ultrapure titanium atmosphere was conducted.…”

A new surfacing material consisting of the Fe-Si-Cr-Cu-C-B system sparingly alloyed with chromium is proposed for agricultural machine parts hardening by induction surfacing method capable to replace the currently widely used materials like Sormite No. 1, 2, PG-US25/27 and those similar to them. The chromium content in the new material is 4.3 %, which is 3-8 times less than that in analogs. The new material was obtained metallurgically, its phase, chemical composition and properties were investigated. The main phase of the alloy is Ferrosilide FeSin, along the grain boundaries of which a carbide phase is precipitated represented by small particles of Cr2C3, Cr7C3 carbides of regular and acicular shapes, as well as large particles of special chromium carbides (Cr,Fe)7C3, (Cr,Fe)23C6. In terms of the relative content, the carbides present in the new material can be conventionally arranged in the following series: (Cr,Fe)23C6 > (Cr,Fe)7C3 > Cr7C3 > Cr2C3.
