 In this work, research was carried out on the physico-chemical processes of forming new composite coatings that were applied from PG-H4 powder and PG-H4 powder with the addition of (Ti, Cr) C, FeTiO3, ZrB2. The results obtained in the work allow to improve the functional characteristics of the coatings, wear and corrosion resistance (KP) on the basis of materials and compounds with amorphous and nanocrystalline structure, and on the basis of the obtained results, the compositions of the KP have been determined which provide for increasing the cohesive strength of the spray layer and stability to wear, corrosion, absorption of neutron radiation, as well as improvement of durability and biomedical characteristics, development of technologies for applying KP with control of their structural state and composition, with an assurance of obtaining the specified functional properties. The principles of creating new materials based on amorphous coatings, which were applied from PG-H4 powder and PG-H4 powder with the addition of (Ti, Cr) C, FeTiO3, ZrB2 in the conditions of gas-thermal and magnetron sputtering, were formulated. The results obtained in the work allow to increase wear, corrosion resistance of parts and products.
