The effect of the chemical activity of the implanted element to metal alloy components on the formation of surface layers under ion irradiation

The paper comparatively studies the effect of implanting O+ ions into the Cu50Ni50 and Cu56Mn44 alloys and M0 copper, as well as N+ ions into the VT6 titanium alloy, the 03Kh17N12M2T stainless steel, and Armco iron, on the formation of the chemical composition and changes in the structural and phase state of the surface layers. It is shown that, under conditions of implantation of ions of chemically active elements, the accumulation of the implanted impurity, the formation of chemical compounds, and their precipitation in the form of phase inclusions are determined by the chemical activity of the implanted element to the alloy components. The results obtained will allow the further development of scientific foundations for the formation of the chemical and structural-phase state in materials under nonequilibrium conditions of ion implantation.
