The effect of ion-implantation processing of N 2 + ions in aluminum alloys 1160, 1190 and 1420 on their microhardness, stresses of II type and microstructure is discussed in this article. During research, prototypes of aluminum alloys were hardened by ion implantation in the accelerator. The implantation mode, selected from literature, was used to test the possibility of hardening aluminum alloys by implantation with N 2 + ions. The ion beam was scanned in a horizontal plane at a beam height of 400 mm. The residual pressure in the working chamber was maintained 5·10 −5 mm Hg. The parameters of the irradiation regime are the following: energy - 5 keV, dose - 10 18 ion/cm 2 , temperature - 200 °C. The strength characteristics were studied by the methods of measuring microhardness, residual voltage in the surface layers of implanted samples. A micro X-ray diffraction analysis was also performed.
