Influence of ion irradiation on structure, absorption capacity and corrosion properties of nanosized metal compositions

Моделі генерації дефектів

It is shown that the method of bombardment of a nanothick vacuum-condensed metallic substance with low-energy ions is a promising tool for the purposeful formation of such gradient distributions of structural-phase states that provide new properties. New methodological approaches have been developed in the structural analysis of nanoscale materials using synchrotron radiation (with a photon flux density by 12 orders of magnitude, and an exposure duration 150 times shorter than provided by traditional methods of X-ray structural analysis).

Physico-chemical basis for strengthening of the light structural alloys surface by ultrasonic shock treatment at cryogenic temperatures

Схема УЗУО

Essentially new scientific knowledge has been obtained on the physico-materials science basics and the laws of the surface layers hardening of the light structural alloys by ultrasonic shock treatment (UST) at cryogenic temperatures. These regularities are due to the suppression of the dynamic return processes and dynamic recrystallization, as well as the effect of the dislocations annihilation under the action of the deep cooling factor.

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.
