Creation of methods for plastic shaping of structures from a new welding alloy of the Al - Mg - Transition metals - Rare earth elements system with high mechanical properties for aerospace engineering

Methods have been developed to ensure high mechanical properties during plastic forming of structures of a new welding alloy of the Al - Mg- Transition Metals - Rare earth elements system for aerospace engineering. A two-stage approach to deformation has been developed, when at the first stage deformation is performed under conditions of large shear deformations for a more uniform redistribution of phase components and a decrease in the size of the grains - homogenization of the material due to mechanical action, and at the second stage - the formation of the structure.

Scientific principles and patterns of electrochemical procceses of formation of ordered nanoscale and microlevel chemotronic materials

The created scientific bases and regularities of electrochemical formation of ordered nano- and micro-level materials of hemotronics are based on a clear separation of the influence of the charge transport mechanism of the limiting stage of the electrochemical process on the stratification of the structure of the surface oxide and metal phases of the electrode. The structuring of semiconductor phases is governed by the ratio of gradients of the electric field and charge carriers in liquid and solid phases.

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

Дифузійний шар на сплаві ВТ6 після нітроцементаціі при Т = 900 ° С. х1000

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.
