Annotation: The process of plasma electrolytic oxidation under different conditions and the influence of certain process parameters were studied. It has been established that almost any organic compounds can be oxidized (mineralized) to CO2 and H2O on the surface of TiO2. In order to further capture of chemically hazardous substances, we use a photocatalytic air purification method in which titanium oxides are used as a photocatalyst. Therefore, further work continues on the use of oxide catalysts on titanium alloys and their subsequent installation in existing absorbent filters of the collective protection system for stationary structures and armored vehicles for efficient neutralization of chemically hazardous substances. Further work is being done on the use of oxide catalysts on titanium alloys with the further improvement of the system of collective defense of stationary structures and on armored vehicles for the effective neutralization of hazardous chemicals.
