Formation of gradient states in nano layered metal film compositions via processes on the outer surface

Laws of energy induced diffusion phase-structural transformations in film functional-gradient materials with significantly different thermodynamic and crystal-chemical properties of the layers (V-Ag, Pd-Ho, Ni-Cu-Cr, etc.) were determined.
“Diffusion pump” effect was determined for investigated nanothickness materials: physical and chemical processes on outer surface thermodynamically determine diffusion phase formation in the bulk during energy impact in argon-, nitrogen-, oxygen-, hydrogen- containing atmospheres and in vacuum of 10-3 Pa, 10-7 Pa.

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.
