A mathematical model is proposed for the destruction of electroexplosive W–Cu, Mo–Cu, W‒C–Cu, Mo–C–Cu, Ti–B–Cu, and TiB2–Cu composite coatings under spark erosion associated with the opening of electrical contacts. The model describes the evaporation of the electrodes under the action of the heat flux due to sparking when the electrical contacts open. In this model, the resistance of the electrical...
The surface planarization of nanoporous SiO2 is made by method of atomic-molecular layer deposition of TiO2 nanofilm in different modes. A penetration of TiO2 in nano-pores of SiO2 is controlled by ellipsometry.
Modification of a titanium surface layer with yttrium is performed by a combined method providing electroexplosive alloying and subsequent treatment by a high-intensity electron beam. Alloyed layer elemental and phase composition, defect substructure, mechanical and tribological properties are determined. Saturation of a titanium surface layer with atoms of yttrium, oxygen, and carbon is revealed,...
