Bovsunovsky E. Cleaning and anticorrosive processing of aircraft elements using native materials

The subject of research was the process of cleaning by high-speed multiphase multicomponent flows and corrosion-resistant coating based on natural materials. The aim of the work was development of the aircraft elements' cleaning by aerosol gaseous dynamic suspension methods with justification for using of natural materials and providing operational properties after processing. Key data were obtained on the basis of the following research methods: optical and scanning microscopy, Auger electron spectroscopy, standard methods of determination of the corrosion rate and fatigue. The possibility of intensification of liquid aerosol particles interaction with contamination layer are proved. Research of cleaning process by aerosol gaseous dynamic flows is made. The dependence of the cleaning effectiveness on the running parameters of the flows is determined. The math model of thermo-physical materials' surface condition under the influence of ice grains flow on the basis of solution of the differential equations of the two-phase environment movement is developed. The ecologically safe technology of the aircraft elements' cleaning by aerosol gaseous dynamic suspension method of processing is developed. Analyzed the process of implementation of natural components of corrosion-resistant material in metal surface and also the phenomenon of rising corrosion resistance of metals' surfaces after the processing by different working mixtures.
