Research of mechanical properties of composite material based on titanium nickelide with a titanium surface layer depending on magnetron sputtering time

Abstract

Abstract The regularities of the titanium surface and transitional monolayers formation using magnetron sputtering and ion bombardment depending on the deposition time, adhesion parameters and mechanical characteristics are investigated. Saturation regions of the surface and transition layers are noted. The transition layer provides high adhesion of the surface layer to the substrate. The application of a titanium surface layer to a nitinol reduces elongation and yield strength but increases tensile strength, and as the deposition time increases, the elongation decreases very slightly, and the yield strength and strength increase.
