Description
Summary:The N + ion implantation effect on the surface morphology, nitrogen accumulation, formation of chemical compounds, and structural and phase state of 03Kh17N12M2T steel and VT6 titanium alloy surface layers has been investigated. Irradiation with N + ions results in nitrogen accumulation up to 17 at % in stainless steel, and the formation of chemical compounds, such as CrN, Cr 2 N, MoN, TiN, and Fe 4 N, in the form of small clusters with the crater-shaped surface. Nitrogen in the titanium alloy is accumulated up to 32 at % to form titanium nitrides, in particular, TiN, in the form of phase inclusions, distributed over the entire surface. The surface morphology of stainless steel is shown to depend on sputtering processes, while that of titanium alloy is shown to depend on the formation of numerous titanium nitride inclusions.
