Developing of the aircraft’s wing construction elements lifetime prediction method duringmacrocracksinitiation stage with kinetics of scattered damage accumulation

The main result is a qualitative and quantitative assessment of the impact of complex operational and constructional and technological factors (geometric dimensions and the degree of plastic deformation of the material) on the parameters of the cyclic strength of elements of the power structure aircraft with functional openings in its infancy macrocracks taking into account the kinetics of accumulation of scattered damage.

Establishing patterns of formation of diffusion coatings on alloys and the relationship between their composition, structure and properties

Showing an increase tribotechnical characteristics of titanium alloys in terms of friction without lubrication, abrasion wear, heat resistance, corrosion resistance the surface after diffusion saturation with nitrogen, carbon, oxygen, chromium, aluminum.

The possibility of intensification of diffusion saturation by introducing into the reaction space activators and activation of surfaces prior Magneto-abrasive treatment that is saturated. This reduces the saturation temperature of titanium and its alloys to 550-900 0C saturation and reduce time to 2-3 hours.
